Rule and Control
The dressing of the cutting block is necessary when it has been cut
into too strongly by the cutting knife or when two different knife shapes
have worked on the cutting block. See illustration b.
The dressing of the cutting block must be conducted very precisely and
may only be done with a faultless, straight bastard file.
The illustration c shows a badly filed, the illustration a a correctly filed
cutting block.
As can be seen in the illustration a, the cutting block must be filed so
that the impression of the knife blade can be seen everywhere very
finely and precisely uniform.
ATTENTION !
As seen in the illustrations, the cutting block must touch parallel on
the cutting knife in order to achieve a uniform distribution of the
cutting pressure.
One-sided cutting pressure, particularly in the area of the eye, can
lead to a breaking-out of the cutting knife.
