Model 325 is designed to sharpen either Straight edge or Serrated
edge blades.
1. Sharpen Serrated Blades Only in Stage 2. Do not sharpen serrated blades in Stage 1
until you read section titled Procedure for Sharpening Serrated Blades.
2. Straight Edge Blades are sharpened in Stages 1 and 2. Start in Stage 1 if the knife is
being sharpened for the first time or if the knife is very dull. See following Section for
more details.
PROCEDURE FOR SHARPENING STRAIGHT EDGE BLADES
STRAIGHT EDGE BLADES: SHARPENING FIRST TIME
Before you turn on the power, slip a knife blade smoothly into the slot between the left
angle guide of Stage 1 and the elastomeric spring. Do not twist the knife. (See Figure 3.)
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 (Figure 3) by slipping the blade between
the left angle guide and the polymeric spring while pulling the blade toward you and
simultaneously moving the blade downward in the slot until it engages the diamond
coated disk. You will hear it make contact with the disk. Insert the blade as close as
possible to its bolster or handle. If the blade is curved, lift the handle slightly as you
sharpen near the tip of the knife, keeping the blade edge approximately parallel to the
table. Sharpen the entire blade length. For an eight (8) inch blade each pull should take
about 5 seconds. Pull shorter blades through in 2-3 seconds and longer blades in
6 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 contact
with the wheel – added pressure does not speed up the sharpening process.

guide and elastomeric spring. Alternate individual
pulls in left and right slots.
