Press the switch, on the lower right front of the sharpener, to “ON”. Hold knife with the illustrated
grip shown in Figure 4. Place the heel area of the knife blade in the left SHARPENING slot of
Stage 1.
Stage 1
Using a secure yet relatively loose grip, pull the knife toward you allowing the magnet to position
the blade at the proper sharpening angle. Let the magnets control blade angle. Apply light to
moderate downward pressure on the knife blade. Do not apply excessive pressure or you will
stop the orbiting action. Keep the blade level as you pull it through that slot. After you pull the
knife through the left SHARPENING slot, place the knife in the right SHARPENING slot and pull
through in the same manner. Repeat these two (2) steps 15 to 20 times alternating left and right
slots. With relatively new knives, these 20 passes (on each side), will be sufficient to reangle
(“Break-in”) the factory edge.
You can verify that the “Break-in” process is complete by moving your finger carefully across
and away from the edge to feel for a burr. Any burr will be present on the last unsharpened side.
When a burr forms on each successive stroke the “Break-in” process is complete. With most
knives the burr is relatively easy to feel; however, with harder knives the burr will not be as
evident. With very dull knives or very thick knives, more than twenty (20) pulls on each side may
be required to “Break-in” the knife.
You should take approximately three (3) seconds for each pass to pull a 6” long knife through
each slot. A longer blade will require more time; for example take five (5) seconds for a
10” blade. To sharpen the tip area of the blade lift the handle slightly as the curved portion of
the blade moves through the sharpening area. Keep the edge portion of blade being sharpened
nominally “parallel” to the table.
NEVER PUT THE TIP OF THE BLADE INTO THE SLOT FIRST AND
PUSH THROUGH.
With a new sharpener some diamond particles may tend to “grab” the knife. Less downward
pressure on the knife and “conditioning” of the diamond particles will minimize the tendency for
this to occur. (SEE “SUGGESTIONS”)
Before leaving Stage 1 pull the knife through each slot with four (4) relatively fast pulls—
about one (1) second each, alternating between the left and right SHARPENING slots. This will
complete the “Breaking-in” process.
Stage 1. “Breaking-in” knife in Stage 1 will take 15 to 20 passes through each slot, alternating left and right slots.
Subsequent resharpenings require fewer passes in Stage 1. Apply light to moderate downward pressure.
