center line of the slot as you sharpen. Apply
about 3-4 pounds pressure on the blade in
Stage 3. Make smooth consistent strokes
while maintaining recommended downward
pressure and make certain the disks
are turning.
RESHARPENING THE KNIFE EDGE
Follow the procedure described above for
Honing/Polishing, in Stage 3, making two to
three (2-3) pairs of back and forth strokes
while maintaining recommended downward
pressure. Listen to confirm the sharpening
disks are turning. Test edge for sharpness.
Generally you should be able to resharpen
2 or 3 times using only Stage 3.
SERRATED BLADES
Serrated blades can be sharpened in Stage
3. Center the blade in the slot of Stage 3
and make two-to-three (2-3) back and
forth stroke pairs. Test the edge and if
necessary make another 5 full strokes.
If the blade to be sharpened is very dull,
first make two full strokes (back and
forth pairs) in Stage 1 or 2 (depending on
the knife being a 15° or 20° blade) and then
make two-to-three (2-3) paired strokes
in Stage 3. Because of its nature, a serrated
knife will never appear as sharp or cut
as smoothly as a straight edged blade.
Caution: Do not make many strokes in Stage
1 or 2, which can quickly remove metal from
a serrated edge.

TEST FOR SHARPNESS
To test for sharpness and cutting ability of
your knife, hold a sheet of paper vertically
by its upper edge and carefully cut down
through the sheet a small (but safe) distance
from your fingers. A sharp edge (on a straight
edge blade) will cut smoothly without tearing
the paper.
Alternatively try cutting a tomato. The
knife should penetrate the skin of the tomato
and cut through it on the first pull without
applying significant force to the knife.

from state to state.
For optimum results center the blade
(left and right) within the slot and keep
the length of the blade aligned with the
center line of the slot as you sharpen. Apply
about 3-4 pounds pressure on the blade
in Stage 3. Make smooth consistent
strokes while maintaining recommended
downward pressure and make certain the
disks are turning.
TO SHARPEN EURO/AMERICAN AND
OTHER 20° EDGE KNIVES
(Use stage 2 and 3)
Follow the general procedures described
above, but sharpen first in Stage 2. You
should use only Stages 2 and 3 (Polishing &
Serrated) as follows:
Sharpening (Use Stage 2)
Position the blade in the Stage 2. Center the
blade (left and right) in the slot so that the
face of the blade does not touch either side
wall of the slot. Slide the blade repeatedly
forward and back toward you along its
full length. Apply only modest downward
pressure as it is sharpened. (Avoid excessive
downward pressure on blade that might
damage the sharpening elements.) Unless
the blade is very dull, twenty-five (25) back
and forth full strokes will likely suffice.
Otherwise continue sharpening (back
and forth strokes) until the knife is sharp
enough to cut paper well or slice easily thru a
tomato. If the knife is very dull, one hundred
or more full strokes may be needed, the
first time,to fully sharpen in this Stage. This
completes the first sharpening step. Proceed
to Honing/Polishing.
Honing/Polishing (Use Stage 3)
If the knife is correctly presharpened in
Stage 2 , then only 2-3 back and forth stroke
pairs in Stage 3 will complete the small
second bevel and the edge will be very sharp
and effective. It should cut paper smoothly
allowing you to make straight or curved
cuts easily.
For optimum results center the blade
(left and right) within the slot and keep
the length of the blade aligned with the
