Sharpenable hand saws
In principle, all saws can be sharpened themselves - except those with specially hardened teeth. These teeth are then harder than the files and would remove material from the file instead of becoming sharp.
In ordinary hand saws, however, such specially hardened teeth are not quite as common as replaceable saw blades.
These tools can also be sharpened with special tools (diamond files), but you must bring the saw to a sharpening service. Even that is not possible.
Important when sharpening
use suitable files (toothing of saw, ie observe tooth spacing) ab dress in time immer check sharpening after sharpening
- correct tooth form if necessary
- always pay attention to saw geometry (LS or QS)
- pay attention to the correct filing angle
- saw correctly clamping
- Suitable files
- A file must always be selected to match the tooth pitch of the saw. The tooth pitch is usually given in saws in TPI (teeth per inch, also ZpZ), if necessary, you have to convert that to millimeters.
Spacing in mm
|During dressing, teeth are brought to the same length. For this one usually uses a flat file. It is always judged by the shortest tooth of the leaf.||Chamfer|
The width of the chamfer can vary individually, but usually around 1.5 times the saw blade thickness is used as the cabinet width. Cabinets (or restraints) prevent the saw from getting stuck later. Korrig Correct tooth form
Dressing can adversely affect the tooth shape. It must therefore be corrected with the file again so that the teeth are tapered and have no head surfaces.
Observe saw geometry
Each saw blade has a specific profile and geometry. Saws can be designed, for example, for longitudinal and cross sections to the fiber. The saw profile must always be kept as it is.
Correct filing angle
Teeth must be sharpened at the correct angle. For beginners, a file guide with attached protractor is recommended. Ein Clamp the saw correctly
The saw must be clamped in such a way that the teeth just barely protrude (eg with the vise). If you hone more frequently, it is worth buying a separate file for clamping the saw in any case.
