Sharpening Features
Any saw sooner or later begins to wear out. Rather, its canvas wears out, in which the teeth are blunted. And they are the main cutting element of any manual model. Sharpening saws is a very responsible process, as sawing can be performed in different ways, and this must be taken into account. You can restore the cutting ability of the teeth by sharpening them with files or files, and you need to monitor not only their sharpness, but also such parameters as the magnitude of the angles, steps and height. And for this you should adhere to a number of rules:
- The saw blade should be tightly fixed in a special tool.
- For sharpening you need a file with a fine notch or a file.
- When sharpening with your right hand, you need to hold the file handle, with your left - hold its end, directing the file itself to the teeth.
- Press the teeth smoothly and evenly.
- Metal from the edges of the teeth should grind to the same thickness.
- Burrs on the edges of the teeth must be removed, as they become dull over time and tool performance will decrease.
- The direction of movement of the file depends on in which direction the tool is sawing - longitudinally or transversely.
After sharpening the saws, you need to evaluate their sharpness. Whatever model you choose, it is important that they are universal, that is, they fit different building materials.
