Model 120 is designed to sharpen either Straight edge or Serrated edge blades.
1. Sharpen Serrated Edge Blades only in Stage 3. Do not sharpen serrated blades in Stages
1 and 2, as that will unnecessarily remove more metal from the serrations. See Section titled
Procedure for Sharpening Serrated Blades for more details.
2. Straight Edge Blades can be sharpened in all three stages, however, use of Stage 1 may
be necessary only if the knife is very dull or if you wish to create an edge with extra "bite".
See following Section for more details.
PROCEDURE FOR SHARPENING STRAIGHT EDGE BLADES
STRAIGHT EDGE BLADES: SHARPENING FIRST TIME
Before you turn on the power, remove the cover positioned over Stage 1 and 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.) (Retain the Stage 1 cover as a ready reminder of the sharpening steps.)
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 your knife is already reasonably sharp, skip Stage 1 and go directly to Stage 2.) If
you are sharpening a knife for the first time or if the knife is very dull, 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 4 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 you should 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 modify or speed the sharpening process.
To ensure even 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. In each stage, make an equal number

and elastomeric spring. Alternate left and right slots.
