The Cutting Edge in Precision Sharpening

HELPFUL TIPS TO REMEMBER

Always keep the tip/toe pointed to the center
1
of the D.I.S.C.
2 Always keep the handle (not the shank) of the instru-
ment parallel to the Instrument Reference Lines.
When sharpening instruments, make sure that only
3
the cutting surface of the working end (as compared
to the shank) is touching the stone to avoid weaken-
ing the integrity of the shank.
4 Avoid re-tipping of instruments, as this can cause
stress fractures of the handle.
5
No lubrication necessary using the D.I.S.C.
6
From time to time, clean the ceramic stones using
a mild abrasive pad (without cleaners/chemicals)
under running water.
Keeping the wrist stiff, use a pull-stroke with moderate
pressure (repeat 5 or 6 times).
Keeping the wrist stiff, use a pull-stroke with moderate
pressure (repeat 5 or 6 times).
Lower the instrument handle in a clockwise
manner until the stone is in optimal contact
with the cutting surface (avoid going too low
and making contact with the shank of the
instrument). While holding the instrument
in this position, turn the protractor dial until
the Instrument Reference Lines are parallel
to the instrument handle. Sharpen in the
usual manner.

On a curette, roll the instrument as you finish
your pull-stroke to avoid sharpening the toe
of the instrument.
Change the dial setting for the
second cutting surface (Example:
"d" for a 204S Scaler). Notice that
the Instrument Reference Lines are
now going down from left to right.
If the instrument has two cutting surfaces, hold
the instrument so that the cutting surface is
perpendicular to, and below the stone, with the
tip/toe pointing towards the protractor. Raise
the instrument in a counter-clockwise manner
until the stone is in optimal contact with the
cutting surface (avoid going too high and mak-
ing contact with the shank of the instrument).
While holding the instrument in this position,
turn the protractor dial until the Instrument
Reference Lines are parallel to the instrument
handle. Sharpen in the usual manner.

*There may be slight variations in setting with other manufacturer's instruments. You can
fine tune your instruments settings by following the directions for unlisted blades. **As you
pull the disc shaped scoop end across the stone, turn it so that it sharpens around the scoop.
At the end of the sweep, you should have turned the scoop 2/3 around. Now, sharpen on
other side the same way. You do not want to finish one side at the top of the scoop, or it will
start to become a point.
Move the instrument to the other side of
the protractor dial - sharpen the cutting
surface with a moderate pull-stroke (keeping
the wrist stiff) - notice that the instrument
handle will be below the stones.
Identify the dial setting(s) and
record them above.
