elements must now be equal in
length and width.
8. After every third sharpening, the
sharpness depth (depth limitation)
must be checked and the height filed
with the aid of a flat file. The depth
limitation should be set back about
0.65 mm from the cutting tooth.
After the setting back of depth limita-
tion, round it off a little at the front.
