Knife from a hacksaw on wood: step.By.Step instructions for yourself

Want to create a unique knife? You need a wood cutter or a sharp blade for hunting? Make a good product with your own hand more than real. The main thing is to have the skill of working with metal and know what you want.

We make a knife: where to start?

First prepare all the necessary details and tools, add them in one place. Decide which material you will use. If you need a sharp and strong product. Make a knife from a saw.

Take the workpiece. Wood or metal saw canvas is best suited for these purposes. As a material for the manufacture of a handle for a blade, use a tree (any, at your request), textolite, plexiglass.

What tools will be needed in the process of making a knife?

To start work and make a knife from a saw on metal, you will need:

  • File;
  • Electric sharpener;
  • Electric drill;
  • Marker;
  • Ruler;
  • Sandpaper;
  • Paste for polishing surfaces;
  • Copper or aluminum for rivets.

How to make a workpiece?

Let’s figure out how to make a knife from a saw. Prepare a metal canvas for making a blade. Draw on it the workpiece of the future tool, using a marker for these purposes.

Remember that the knife is considered a cold weapon if the length of the blade exceeds 2/3 of the total length of the product. If you are incorrectly designed a knife from a saw and it is regarded as a cold weapon. Wait for the punishment.

How To Cut Metal. Ace Hardware

Having outlined the contour of the future product, take up the shape of the form. It is important to draw a shape so that the cutting part of the future product is placed in the area of ​​the teeth of the saw. Due to the cutting of the saw, if you do the butt in this place, you will have to do additional work to grind the bulge.

What needs to be taken into account when starting work

Do not start gritting a knife without training. Take a regular piece of metal and try to process it. To spoil the piece of iron is not as scary as losing a good blank. You must not only regulate the pressure of pressure when turning, but also monitor the temperature so as not to overheat iron. High temperature not only spoils the type of metal. Even if it does not change externally, its structure can seriously suffer: the metal will become much softer and more fragile. A knife from a circular saw made of low.Quality metal will have to be sharpened more often.

To check whether iron has begun to overheat, drop a couple of drops of water to the workpiece. If she immediately evaporates, rather cool the workpiece for the future blade. To avoid possible troubles associated with overheating of the metal, put a container of water near the machine and periodically cool the future knife from the saw.

Working with the workpiece

Having formed the basis of the future knife, proceed to the most important and complex stage of work. The removal of the descents. Descent is a surface on a knife, smoothly narrowing towards the blade. The purpose of the knife directly determines the angle and the width of the descents. Therefore, choose the average value if you want to get a universal knife from the saw.

Before starting work on the machine, draw the proposed descent on the metal canvas using a marker for this. Grind carefully, slowly, so as not to spoil the future knife. It is recommended, as in the previous step, to practice on a spare part. Descents should be symmetrical and lie at the same angle from both sides. In this case, the blade should be nobility: leave the indent about 0.25 mm.

To hone the blade, use sandpaper. For such purposes, sandpaper 8-10 stiffness numbers is best suited. It is better to sharpen a knife from a saw on metal on a wooden bar. To prepare an impromptu sharpener, take a bar and glue the sandpaper to it.

Using large sandpaper, you will give the blade the necessary severity, and taking a smaller one, polish the metal blade completely.

At the final stage of processing, polish the blade. Pull the same wooden block with felt or skin, grate with gog paste and polish until you reach the desired effect.

How to make a knife handle

The easiest way to glue a handle of two cut and prepared pieces of wood or plexiglass. It is much easier to make it than fix it on a knife tail. Naturally, you can choose an unpretentious option and wrap the handle with electrical tape, but why try so much in order to ultimately spoil the aesthetic appearance of a knife?

And then the most crucial stage of work comes. Since you will have to drill in the shank of the knife, the canvas can easily burst. So be vigilant and careful.

Steel is solid, but at the same time fragile material. With a uniform pressure distribution, when the saw is in work, it is almost impossible to break it. But with point drilling, the pressure increases, and the metal can easily split. Therefore, it is better to drill a hole at low speeds of the machine and do not forget to add oil to the drilling place. In this case, a screwdriver is an ideal tool for fulfilling the set target, since it has less speed, then the possibility of breaking the part is not so high.

Having completed the previous step and making holes in the handle, drill the same in the halves of the handle. Make a copper or aluminum rivet. For insurance you can glue the area where there will be a rivet, glue, but it is better if you have epoxy resin.

Is it possible to simplify the process?

Masters say that the hole can be done without the use of drilling tools. The blade with the shank is covered with a layer of varnish. Where there should be a hole, you need to clean the surface of the varnish. Place the knife from the saw on the wood in the electrolyte solution and lower the wire with a negative charge into the container with the blank, and connect the positive to the power source, as which you can use the usual battery.

As a result of such an effect, you get a hole in the metal, however, it will not be perfectly round, but it will definitely not be possible to damage the blade in this way.

Other methods of processing parts

If for some reason you can’t make a knife from a saw on a metal, there is no necessary material-replace it. A car spring is well suited for making a blade, the metal of which is softer than that of a saw. To process such a workpiece, you do not have to use the sharpener, but you will need a saw for metal to cut out the shape of the blade. Since the metal is easier to process, the edges of the workpiece can be fitted with a file. This way will have to work on the manufacture of a knife longer, because each processing stage includes manual work.

Technical characteristics of hacksaws

The state standard specifies what materials canvas, pens can be made of, what should be the connection of the working surface with the handle. The permitted dimensions of the tool and its individual parts are also indicated. There are requirements for sharpening and breeding incisors, the minimum-permitted sharpening indicator to the front and back of the tool.

What you need to know about an electric saber’s file

Do not think that wooden wood is an analogue of a manual model, only with an electric drive. Thanks to the original design, the canvas in such units moves in two planes.

In addition to the traditional reciprocating movement, the canvas still fluctuates according to the principle of the pendulum. This reduces the wear of the cutting edge, and also increases the capabilities and resource of the apparatus. It is the average option between jigsaws and chain saws. With such a tool, you can cut wood, metal, stone and many other materials, the main thing is to choose the corresponding shift blade.

Before choosing an electric wood on wood, you need to understand for yourself what exactly you want from this unit. And find out which is better a knife.Haired woman will allow a thorough study of the instructions.

does, wood, hacksaw, look

The most important are the following characteristics:

  • Initially, this is engine power. A device with a capacity of up to 600W is suitable only for thin branches or small carpentry works. For more serious tasks, there are hacksaws up to 1 kW. Professional tool starts from 1.2 kW.
  • It is preferable that the canvas changes without a key, so much more convenient.
  • The presence of a cut depth limiter is a very useful option. It can also be adjusted with or without a key, the second option is better.
  • In order not to constantly look for a corporate canvas, it is better to take an unit with a universal head, into which you can fix any blade.
  • Speed ​​regulator will greatly facilitate work with different materials.
  • The shutdown function of the pendulum will make a cleaner cut and remove vibration.
  • For ceiling work, the possibility of changing the angle of inclination of the blade will be useful.

The video in this article gives additional tips on the topic.

Main settings

The efficiency of using a hacksaw on wood largely depends on its technical characteristics. The main ones are:

When choosing a tool, you need to pay attention to each element of the characteristic. Only in this case you will not have to regret the purchase

The material of the canvas

The canvas of modern woodcuts from high.Quality instrumental (alloy) steel with a high content of carbon and silicon (65g, 8XF, U7 U10) is made. Hardness should be at least HRC 45. There are also models that use a combined, more wear.Resistant canvas with a cutting part (teeth) having increased hardness (HRC55 60).

Length and shape of the canvas

On the domestic market you can find hacksaws on wood with a length of 250 to 650 mm with a step, a multiple of 25 mm. This parameter is set by GOST 2615-84 and depends on the distance between the teeth.

Otherwise, it will be uncomfortable to work with a hacksaw, since a short canvas will seize the woods inside.

As a rule, hacksaws with a narrow canvas have a length of not more than 350 mm and are equipped with a large number of small teeth. Universal instruments are equipped with canvases of about 500 mm long with medium.Sized teeth. Khosuvka with a wide canvas is made with large teeth located at a great distance from each other (large step), their length can reach 650 mm.

Traditionally, a wood saw has the appearance of a triangle narrowed on one side. Such a tool can work with any kind of wood. In addition, there are hacksaws adapted for work, for example, with tree branches or other objects located from the sawmill at some distance. They have a rounded shape and are small in weight.

Tooth size and shape

The sizes of the teeth (step) of the hacksaw canvas directly affect the performance and accuracy of the tool. The larger the teeth, the higher the speed of work, but the accuracy and quality of the cut worsens. The use of a saw with small teeth, on the contrary, guarantees a clean and even cut, but the speed drops.

The accuracy of the cut is determined by the number of teeth per 1 inch of the length of the canvas (TPI coefficient), that is, their location density. Its value is marked on the side surface of the canvas (for example, 7×1 ″ or 7tpi). The more tpi, the less step. So, 2TPI = 12 mm, and 12tpi = 2 mm.

When choosing a hacksaw on wood, it must be borne in mind that the minimum thickness thickness should be greater than a step of three teeth.

does, wood, hacksaw, look

Significant when working with a hacksaw on wood is the appearance of sharpened teeth. The teeth sharpened on both sides and having the form of an acute or isosceles triangle are considered standard.

Type of the handle

Type of the handle and the material from which it is made largely determines the convenience of working with a hacksaw on wood. It is best to work with a saw equipped with a whole plastic handle with rubberized fingers. The handle made of two parts is less convenient, since it does not have sufficient rigidity.

There are also hacksaws with braid handles. They, as a rule, equip universal and ray saws, in which canvases can be changed during work.

Technical characteristics of the hacksaw on wood

Information what the hacksaw consists of is already higher. The characteristics of the working area depend on a number of parameters:

The saw should be made of steel, the brand of which is indicated in GOST 5950-73. When cutting a tree (logs) of a large diameter, it is more convenient to work with a long saw (45-50 cm), since a large number of elements pass through one movement through one movement through the material. A hacksaw up to 35 cm is used for small work, suitable for solving household problems.

Standard width of the blade-10-20 cm. In some cases, a narrow saw is recommended, but the canvas is easily damaged. Therefore, the GOST indicates the requirement to work with the web of the average width.

The characteristics of the teeth affect the parameters of the work, therefore, to increase the speed of the carpenter, it is necessary to pay attention to their appearance. It is more convenient to saw fresh tree with a tool with triangular elements located in 2 parallel rows

Having an average tooth size, she quickly copes with the task, without clogging with sawdust the working area during operation.

You can also get an accurate cut by combining round elements with triangular. The accuracy of the seam depends on the size of the angle between them.

The number of teeth per inch (tpi) also matters. This is a performance parameter for the working area. If you take the same saw length, then with an index 3-6 elements are large, the speed of work is high, but low seam accuracy.

To cut the tree with a saw that has a TPI 6-9 coefficient, you will need more time, but the cut line will be more accurate due to small teeth.

What should be the shape of the handle?

This part of the saw is responsible for convenience when performing work. It is necessary that the chosen tool literally merges with the hand of a person performing construction work and is a truly convenient. A wide variety of plastics can be used to create handles.

Typically, in high.Quality hacksaws, for this, grooves, special recesses and an additional rubberized lining are provided right in the body of the handle.

The use of a hacksaw for metal

Such a canvas is quite universal, due to small teeth, you can saw not only metal, but also many other materials, for example, plastic, materials made of plexiglass or wood.

It should be flexible enough and not stagger to ensure the correct incision. Over time, the operation of the tool blows it and you will need to replace the canvas itself.

General sharpening requirements

Sharpening of a hacksaw is a rather painstaking process in which accuracy is important. To facilitate it, only good files and subfilles with sufficient acute should be used. If the saw has to sharpen often, the best solution would be to start a separate set of tools for this work. Before sharpening it does not hurt to look at the hacksaw tooths. If their shade is darker than the canvas, then they are hot. To sharpen such a hacksaw on a tree will not work.

When sharpening at home, the metal should be removed evenly. An equal number of passages with a file is made for each individual tooth, regardless of how much it was worn before correction. In this case, you cannot change the angle of sharpening set by the slope of the file, or to rotate it around its axis. Movements should be made strictly from itself, since it is with this technology that the efficiency of removing the metal of the hacksaw is achieved, and the employee can confidently control the tool in his hands.

In order to prevent additional difficulties during sharpening, the saw canvas should be rigidly fixed in a vice. It is desirable to have source of direct light, which will not peer into the results of the work.

How to work with a two.Handed saw and making a comfortable hacksaw with your own hands

If the chainsaw has broken, the gasoline ended or the manual hacksaw is not suitable for the cut of a thick log, then for this there is such a tool as a two-handed saw, better known among the people, like friendship-2.

Previously, such a device performed work on sawing thick logs and large trees. Today, friendship-2, although it has reduced the position of popularity, it continues to be used in the household.

To simplify the use of a two.Handed saw on wood, consider the process how to make the tool even more convenient and practical, and find out the effectiveness of the use of the cutting device.

Why is the file called “Friendship-2”

Surely everyone knows this type of chainsaw, which is called “friendship”. The next model of the chainsaw was supposed to receive the appropriate name with the prefix “Two”, but the name “Friendship-2” went to such a cutting device as a two-handed saw.

It got its name due to design features. The two.Handed transverse saw is designed to work in pairs, and not just together. In pairs. This means well.Coordinated friendly work by the device, from where such a name actually originated under the USSR.

The Soviet two.Handed saw was popular, since its main advantage is in a low cost.

Drinking thick logs and large trees with a hand hacksaw is not only hard, but this also needs a lot of time. That is why such a type of cutting unit appeared as friendship-2.

Even if now in your garage or in the attic is a two.Handed saw of the time of the USSR, then do not rush to get rid of it. You can not only saw trees and logs, but also make different tools, for example, a knife or a hand saw. If you remembered that in the garage a hacksaw for two handles is dusting somewhere, then it’s time to find out all its advantages and opportunities.

Design features of the file

This tool for two is also called a transverse saw, which belongs to the category of manual devices, and is used mainly for sawing wood materials of different sizes and thicknesses.

For this, the saw has different lengths of paintings. From one meter to two. It is inconvenient to hold such a long canvas, so there are two handles in the design of the device.

Not only in Soviet times, but today the release of two.Handed hacksaws in compliance with standard sizes continues:

The canvas does not have a straight shape, but rounded, which is done specifically to increase the efficiency of sawing, as well as reduce the load. The teeth on the canvases are large compared to manual hacksaws, and their size is 20 mm. Even if you use a meter saw, then working with it is inconveniently inconvenient. There are several reasons for this:

  • Long length does not allow a strong scope to the sawer
  • Large teeth of the saw hardly bite into a tree, and therefore the sawer alone will not cope with the incitement of the cutting device
  • Strong vibration helps to increase the load, as well as a decrease in the effectiveness of the actions performed

Saws with a canvas 1000 and 1250 mm are popular due to the fact that they have a simplified design.

Scabings with canvases of 1500 and 1750 mm were used mainly in industry for sawing building and wood materials.

does, wood, hacksaw, look

In the household, if they meet, then exclusively saws with a canvas 1 m and 1.25 m. They have classic triangular links, the sharpening angle of which varies from 35 to 70 degrees.

  • For sawing dry and frozen logs, it is recommended to use a transverse saw with an angle of sharpening of teeth at 50-70 degrees
  • For sawing soft wood, a tool with prisoning of links at an angle of 35-40 degrees is used

Two.Handed saws with canvases from 1.5 meters have a complex design, which simplifies the use of a large aggregate.

Special sharpening and shape of teeth on large files is needed to perform high.Quality and fast sawing material.

It is interesting! If ordinary hacksaws on wood and two.Handed saws up to 1.25 meters can be sharpened independently, then a hacksaw with a canvas is more than 1.5 meters, which has a complex shape of the teeth, can be hidden exclusively by specialists with extensive experience and experience.

If I fell into the hands of a saw with a complex shape of the teeth, then do not rush to sharpen it at home. If you do not take into account the difference between the shares of millimeters in the complex design of the teeth, then the attempt to restore integrity will lead to the complete damage of the two.Handed saw. The consequences will be approximately as follows:

Why you should NEVER EVER throw away your old hacksaw blades

  • If the difference in the ratio of angles between cutting and cleansing teeth is reduced to one value, then instead of sawing, the canvas will tear the wood and only complicate the physical labor of sawmills
  • If the difference in the ratio of the teeth is large, then the chips from the site of the cut will not be effectively displayed, which will also complicate the work

That is why the sharpening of the transverse saw requires an appropriate and competent approach. The principle of sharpening a two.Handed saw from 1 m to 1.25 m is similar to the process of pulling the teeth of manual hacksaws.

How to saw a two.Handed saw detailed instruction with a description

At first glance, the process of sawing with a two.Handed saw may seem easy and uncomplicated. However, it is only worth the beginner to take up the hacksaw, it immediately becomes clear that this is work for real and strong hands. However, it is not necessary to have a mountain of muscles to properly saw the wood with a saw “Friendship-2”. This needs a little experience, and also understand the principle of work.

It is interesting! Even with the experience of work with short.Made hacksaws, a beginner who picked up a two.Handed saw for the first time, will be unpleasantly surprised. If an experienced saw at the other end of the saw will stand, then the beginner will have a hard time until he masters the principle of operation of the device.

House hacksaws for home and their types

In addition to power tools, in the arsenal a good master should have manual tools. And this is not only a hammer and sets of keys, but also a hacksaw on wood also refers to manual tools, the choice of which is needed by the corresponding approach. It is used exclusively for processing wood. Pruning of trees, preparation of rafters, bars and boards during construction, as well as the manufacture of different structures from woodworking materials. Wood hacksaws are the second most important tool after the hammer, and their choice needs an appropriate approach.

The choice of any tool needs a competent approach. Khosuovka on wood, although it is considered the simplest manual tool, which consists of a cutting part and a handle, but a lot depends on it. This is the speed of achieving the result, and the quality of the cut, as well as the number of physical efforts applied by a person when cutting trees.

Many home masters have old hacksaws of the times of the USSR, who have one important quality. This is reliability. Modern hacksaws are less reliable, but more practical and convenient to use. That is why, if you have an old manual saw on a tree in your garage, then do not rush to throw it away. To restore the performance of the tool, you need to sharpen a hacksaw on wood. However, it is important to consider that the teeth on the tool should be all, otherwise, it is not suitable for further use.

It is interesting! The absence of one or more teeth on a knife on wood not only reduces the productivity of the tool, but also makes its operation unsafe. Indeed, at the place of absence of teeth on the canvas, the load increases, therefore it is not excluded that the material can be broken, thereby injuring the master working as a tool.

If there is an old tree hacksaw in the arsenal, then you can restore its performance, and if it is decided to purchase a new one, then the choice will be needed for the choice. Before choosing, consider the types of hacksaws on wood, how they are and how they differ.

The individuality of the hacksaws

What are the hacksaws on wood? Different models of manual saws are known, but the most used are full of personnel, equipped with cloths for 10-12 inches.

Despite the type of hacksaw, it is important to check that a high.Quality product made from a special, steel alloy is offered.

In the most modern versions. The blade is adjustable in length, which makes it possible to cut off branches of different diameters.

  • The cutting part is inserted into the pillars on the frame.
  • It is exhibited in any location, providing the opportunity to push back and go for a certain need.
  • Among the large selection of types of products, all options have differences: in the shape of a handle; the size of the teeth; sizes and other characteristics.

The buyer needs to take into account his needs when selecting the working part and its dimensions. If you plan to cut boards and remove non-volumetric branches, then you will need a product with a width of the working canvas equal to 28-30 cm.

  • For construction cases, basics are used 45-50 cm, on sale you can find large sizes, depending on which work you need to do.
  • The effectiveness of the instrumentation depends on the ratio. In the wood part, the thickness should be 2 times smaller than that of the file.
  • Then the fly movements are more obtained, so that the intended task will be faster to implement the planned task.

Purpose and types of teeth

The main part of the working element of the structure is represented by teeth. The productivity of the tool is characterized by a different number of teeth, which are also characterized by other properties. An example can be called TPI. The number of teeth that are designed for one inch. A narrow hacksaw for wood or a wide version of the performance is characterized by the following features:

  • A large tooth allows for high labor productivity, but the resulting cut becomes rude.
  • A hacksaw with a small tooth allows you to get a quality cut, however, the task of sawing is significantly complicated.

The most important criterion, taking into account the choice of tooth, can be considered the degree of processing of the material. If you need to get high accuracy of the cut, then the tool with the TPI 7-9 indicator is selected. However, for sawing logs is suitable for a wood hacksaw with tpi 3-6.

Teeth are also classified according to the degree of processing. They distinguish a knee and usual version of the execution, the first is characterized by the fact that it can withstand a rather long effect and at the same time not dull. However, the knee version of the execution cannot be repeatedly sharpened due to a low degree of processing, ordinary metal is sharpened. Therefore, a hot hacksaw after wear is thrown out.

Instructions for proper sharpening hacksaw

Before starting work, you need to tighten your canvas tightly in a vise so that it does not stagger. Having fixed the canvas, take a file and begin to grind the left line on the first clip. At the same time, you need to keep a file at an angle of sixty degrees.

Work as a file with uniform and smooth movements. In the same way, you must sharpen all the left parts of the odd teeth, and then the right. Then we turn the canvas, fix it and pull the cloves of the even row.

After finishing work, you must definitely clean the canvas of burrs with a specialized velvet file.

Overview of the best woodcuts

On the market of the knife stabs on wood are presented in a wide assortment. Among them there are products of both domestic and foreign production that have proven themselves from the best side.

The Zzher Expert saw. A universal tool with which you can carry out both longitudinal and transverse cuts of wood. A 40 cm long canvas has hardened, specially diluted teeth located with a step of 5 mm.

Banco Laplander 396-Lap mini-sawdust is specially designed for use in marching conditions. The narrow pointed canvas has the teeth of the Sandvik XT shape, providing high.Quality cuts of wood both along and across the fibers. The length of the hacksaw in a folded state is 23 cm, and it weighs only 200 g.

Gross Piranha hacksaw canvas is made of high.Quality steel hardness HRC 52. At the same time, teeth hardened to the hardness of HRC 66 have a trihedral shape with laser sharpening and covered with a teflone, the use of which improves the sliding of the canvas and the cleanliness of the cut.

When choosing a hacksaw, you need to pay attention to its marking, study the parameters and, if something is not clear, clarify the seller. After purchase for the tool, you should take care, clean it after work, store in a dry place, sharpen and carry out wiring if necessary. Only in this case it will last as long as possible.

Consider with you manual saws / hacksaw. Their varieties in our time have become quite a few. We will not go into the history of the occurrence of saw in the world and in Russia in particular. But we consider them from the point of view of the design features arising from the application and historical decisions of those companies who have made a significant contribution to the development of manual saws. We hope that deep immersion in this topic, technical features and requirements for saws will now allow you to more competently approach the choice of saws, their operation, sharpening and storage. You will see that the determining criteria for choosing a tool are: application, characteristics, convenience and manufacturer.

Despite the Rapid development of electrical and battery tools, hand saws remain one of the demanded assistants for masters. In such cases such as cutting spikes, making beautiful complex compounds and other small works, a hand saw is still not replaced. And given the active development of the hand-made and the revival of the carpentry, the interest in high-quality hand saws (hacksaws) only increases. Expansion by manufacturers of the Daws line, revival of rarent brands and their replicas, as well as improving the quality of materials and the active entry of Japanese saws into our market. All this helps manual saws to be really useful tools.

Technical characteristics of hacksaws

The state standard specifies what materials canvas, pens can be made of, what should be the connection of the working surface with the handle. The permitted dimensions of the tool and its individual parts are also indicated. There are requirements for sharpening and breeding incisors, the minimum-permitted sharpening indicator to the front and back of the tool.

What are the teeth

Tails such as the type, size and quantity affect the quality and speed of the saw. Identification of the size and number of teeth is carried out due to the special designation of TPI. This designation shows their number for one inch, and this information is located directly on the description of the hacksaw. Hand files are divided into sizes of the teeth of the canvas by:

  • Knife.Cutting wood with a large tooth. This type of tooth allows you to make a gross cut, which also accelerates the work of this product. Such saws are suitable for home or cottages when sawing trees, branches, firewood, boards, etc.P. If you need a hacksaw specifically for such events, then choose a canvas with the size of TPI teeth from 3 to 6.
  • Fabric with small tooth. Their purpose is to carry out work on even sawing materials: laminate, fiberboard, chipboard. For such purposes, you should purchase tools with the size of the TPI tooth from 7 to 9.

There are also differences in the form of the teeth themselves. Consider how the hacksaws are divided in the shape of a tooth:

  • A oblique universal tooth. A hacksaw with this type of tooth is also called longitudinal or oblique. When examining the canvas from the side, the teeth resemble the shape of the hook. It is tightened on both sides of 60 degrees, which allows you to use the tool for both longitudinal and transverse cuts. It is used when sawing large wood materials.
  • A chirper.Shaped tooth. It is characterized by the shape of a rectangular triangle, and is used mainly in shoe.Type saws or in awards. Sawing is carried out only in one direction, and sharpening is carried out across the canvas. Intended for the transverse cut of wood.
  • Dagger tooth. Resembles an isosceles triangle in form, which makes it possible to perform sawing in two directions. The teeth are divorced at an equal distance in different directions. This species is intended mainly for the transverse cutting method, as it is focused on the gap of wood fibers. With the longitudinal method of cutting, the fibers of the tree are split, which slows down the canvas and makes the cutting process complicate.
  • A tooth with a staged vertex. Based on the finalization of oblique and dagger teeth. In this case, the top of the triangle is removed, thereby forming three cutting edges.
  • Wolf tooth. A unique form that was designed specifically for sawing raw wood, where there are complex fibers. The main feature of such products is that the sizes of the depressions between the teeth alternate. This feature allows you to get rid of the clogging of the canvas with large sawdust.
  • Japanese tooth. Is a type of reverse wedge. The thick part is located close to the processed product, so these tools do not need additional wiring. The tooth has an acute angle of sharpening, as well as a large height. Such an instrument ensures high efficiency of cutting in the direction of “to yourself”. They received such a name for the reason that it is in Japan that it is customary to saw in this direction.

Now you know about what criteria it is important to pay attention to when choosing a hacksaw on wood for home use. Of no small criteria are the cost and manufacturer. A good tool will not be produced in the PRC, and its price will not be less than 500 rubles.
