STAGE 2 (SHARPENING) 20° KNIVES
Do not use Stage 1.
Stage 2 will create the primary facet of 20° on the European/American knife. To sharpen,
place the sharpener on the table gripping it securely with your left hand. Push on the power
switch. Insert the knife blade, (Figure 10) near its handle, into the far left slot of Stage #2 and
allow the left face of the blade to rest on the slanted left face of the slot as you pull the knife
toward you. The knife edge should be in sustained moving contact with the internal diamond
abrasive coated disk. Only light downward force will be necessary as you pull the blade
toward you. Listen carefully to insure your knife maintains good contact with the rotating
diamond disk. Take about 5 seconds to make each pull if you have a six inch (6") long blade.
Increase the time of each pull for longer blades or decrease the time for shorter blades.
Make one pull of the blade in the left slot as described above and then repeat the same
procedure in the adjacent (right) slot of Stage 2 (see Figure 11). As you pull the knife through
the right slot, hold the right face of the knife against the slanted right face of the slot. If your
knife, before sharpening, is not very dull you will find that only about 6-8 pairs of pulls,
alternating in the left and right slots of Stage 2, will be sufficient to put a keen edge on the
blade. However, if the knife is initially very dull you may find that 10 or more alternating pairs
of pulls in the left and right slots of Stage 2 will be needed the first time as you reshape and
sharpen the old edge. Always pull the blade toward you. Never push the blade away from
you when using Stage 2. Before leaving Stage 2 it is important to examine the knife edge to
insure there is a small burr along one side of the edge.
Figure 12 illustrates how to check for the burr. Proceed as follows: If your last sharpening
pull was in the right slot there should be a small burr on the right side of the blade edge. If
the last pull was in the left slot there should be a small burr along the left side of the edge. If
there is no burr make another pair of pulls and again check for a burr. Repeat making pairs of
alternating right and left pulls until you create a small burr along the entire edge. (Sometimes
it is easier to create the burr if you pull the blade slower.) Make another single pull and confirm
there is a burr along the edge after each pull. Only then are you are ready to polish the edge
in Stage 3.
STAGE 3 (POLISHING) 20° KNIVES
Since Stage 3 is a manual polishing stage, you can turn off the power switch. If the 20
degree knife is correctly sharpened in Stage 2, only 4-5 back and forth stroke pairs in
Figure 10. Inserting the blade in the left slot of the
Stage 2. Alternate individual pulls in left and right slots.
