A sharpened hacksaw for wood saws itself. this will be confirmed by any professional carpenter or joiner. If you do not agree with this, then it’s time to sharpen the tool.
Sharpening a hacksaw for wood includes setting the teeth of the saw. To do this, there are special ways, as well as improvised tools.
Tooth pliers are a good tool. Its cost can be compared with the price of a hand saw: 300-500 rubles. It is very convenient to use, the removal of the tooth of the saw to the side will be what you need.
Wiring for a hacksaw. It’s also a good thing and is inexpensive. the average price is around 100 rubles. The design is elementary: several slots and an adjustable goniometer. The tooth is inserted into a suitable sized slot, and wiring is carried out by pressure on the handle. The set goniometer ensures uniform wiring.

Technology is simple: the blade is inserted between the two teeth and the ax is turned, the teeth are bent to the sides.
The wiring of the saw can be done with the help of a self-tapping screw. It is safer. To do this, you need a long screw. to make it more convenient to hold. Before work, it needs to be slightly modified. It is necessary to slightly sharpen his hat on one side. to make it flat. This is necessary so that when it is applied to the tooth, it does not slip and does not deform the latter.
The hacksaw lies flat on soft wood (pine, spruce). Holding the screw by the leg, put it on the tooth with a hat and hit it with a hammer. Tooth bends. The operation is carried out through the tooth. After the saw blade is turned over, and the operation is similarly repeated.

For sharpening, the saw needs to be firmly fixed so that when exposed to a file, it does not vibrate. Otherwise, the quality of work will be low.
They fix the hacksaw blade vertically, often in a vice, in makeshift clamps, but if there is neither one nor the other, then you can do without them.
The fixing method without special devices is “on the edge of the workbench”. The hacksaw blade is laid so that only the saw teeth hang from the edge of the table. However, the handles of the saw are always thicker than the blade, and therefore the place next to it cannot be put tightly to the workbench. Therefore, you need to use the corner of the table, and then the handle of the saw will not interfere.

Triangular file with one working side. The profile of this tool is not standard, if on a regular triangular file all sides are equal and working, then this needle file has one working side, and its shape is an isosceles triangle with a very large base.
With this triangular file with one working side, it is convenient to process small or oblique teeth. During operation, it acts only on the surface to be treated; on others, it only glides. There is no risk of grinding off an adjacent tooth.
Plain triangular file. A compact tool that handles most standard wood hacksaws conveniently.
Normal triangular file
