Sharpening the blade, hard-metal blade
The hard-metal blade can be sharpened "lightly" using a diamond file.
Depending on the cleanliness of the wood, as many as 500-1000 bulk cubic metres of
wood can be processed with a hard-metal saw-blade without resharpening.
The best sharpening result and durability of the blade is achieved when the saw-blade
is sharpened using an appropriate grinding machine with a diamond disc.
