Instruction manual V2.2 – 08/2007
6. Fine coarse procedure
After Fine Honing is Complete
Shut off instrument by depressing ,OFF” button. Clean knife and wipe dry care-
fully (Figure 20.1). Where atmosphere is corrosive and the knife is to be stored
for any length of time, lubricate with a good grade of light, neutral oil.
After the knife has been used, only a ,touch up” of the edge, using fine hon-
ing may be sufficient to restore cutting qualities. (Never strop.) Much will
depend upon the type of tissue and desired thickness of the sections. Again,
microscopic examination will assist you in determining what is necessary.
As illustrated in Figure 20.2, fine honing is complete. Note the even width of
the fine facet (from end to end of knife). Small knicks have been satisfacto-
rily removed. Microscopic „S” - shaped lines on fine facet are a normal
result of polishing action and do not affect cutting qualities.
In redressing hone plates the switch will stop the action of the
hone table when the timer runs out only if the knife carriage as-
sembly is in a normal stop position. It is essential therefore, that
the previous cycle be allowed to run to completion and the ,,OFF”
button be depressed to prevent any further movement of the car-
riage.
