PROCEDURE FOR SHARPENING STRAIGHT EDGE BLADES
STRAIGHT EDGE BLADES: SHARPENING FIRST TIME
Always clean the blade free of dirt, oil and food before inserting into sharpener.
Before you turn on the power, slip a knife blade smoothly into the slot between the left
angle guide of Stage 1 and the plastic spring. Do not twist the knife. Move the blade
down in the slot until you feel it contact the diamond disk. Pull it towards you lifting the
handle slightly as you approach the tip. This will give you a feel for the spring tension.
Remove the knife and press the Power Switch. A red "indicator" on the switch appears
when this switch is turned "ON."
STAGE 1
If you are sharpening a straight-edge knife for the first time, start in Stage 1. Pull the knife
once through the left slot of Stage 1 by slipping the blade between
the left plastic angle guide and the plastic spring while pulling the blade toward you
and simultaneously moving the blade downward in the slot until it engages the dia-
mond coated disk. You will hear it make contact with the disk. If the blade is curved, lift
the handle just enough as you sharpen near the tip of the knife to keep the blade edge
in audible contact with the rotating disk. Sharpen the entire blade length. For an eight
(8) inch blade each pull should take about 6 seconds. Pull shorter blades through in
3-4 seconds.
Next, repeat with one full length pull in the right slot of Stage 1.
Note: Each time you insert the blade, simultaneously pull the blade toward you. Never
push the blade away from you. Apply just enough downward pressure to make con-
tact with the disk – added pressure does not speed up the sharpening process.
To insure uniform sharpening along the entire blade length, insert the blade near its
bolster or handle and pull it at a steady rate until it exits the slot. Always make an equal
number of pulls alternating one pull in the left slot and then one pull in the right slot in
order to keep the edge facets symmetrical. Generally in Stage 1 you will find that only
3 to 5 pairs of slow pulls is adequate, but for a duller knife more pulls will be needed.
Before moving to Stage 2 it is very important to confirm that a burr exists along one
Stage 1. Inserting blade in slot between
guide and elastomeric spring. Alternate
individual pulls in left and right slots.
