D.I.S.C.
™
The Cutting Edge in Precision Sharpening
HELPFUL TIPS TO REMEMBER
Always keep the tip/toe pointed to the center
of the D.I.S.C.
Always keep the handle (not the shank) of the instru-
ment parallel to the Instrument Reference Lines.
When sharpening instruments, make sure that only
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.
Avoid re-tipping of instruments, as this can cause
stress fractures of the handle.
No lubrication necessary using the D.I.S.C.
From time to time, clean the ceramic stones using
a mild abrasive pad (without cleaners/chemicals)
under running water.

Turn the protractor dial to the
appropriate dial setting (Example:
“G” for any Gracey 1-10).
Hold the instrument with the handle parallel
to the Instrument Reference Lines. Position the
working end towards the center.
Keeping the wrist stiff, use a pull-stroke with moderate
pressure (repeat 5 or 6 times).
On a curette, roll the instrument as you finish
your pull-stroke to avoid sharpening the toe
of the instrument.
Turn the protractor dial to the
appropriate dial setting for the
first cutting surface (Example: “L”
for a 204S Scaler).
Hold the instrument with the handle parallel
to the Instrument Reference Lines. Position the
working end towards the protractor.
Keeping the wrist stiff, use a pull-stroke with moderate
pressure (repeat 5 or 6 times).
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.
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 cutting surface(s) of
the instrument.
Hold the instrument so that the cut-
ting surface is perpendicular
to, and above the stone, with
the tip/toe pointing towards
the protractor.
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.
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.
Identify the dial setting(s) and
record them above.

*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.
