SHarpenIng tHe CeramIC KnIfe
Ceramic knives will have each of their edge facets sharpened at the standard 15 degrees to
create a total edge angle of 30º. Use only Stages 2 and 3.
SHarpenIng tHe edge In Stage 2 ceramic
Turn ON the power and pull the ceramic blade thru the left slot of Stage 2 Ceramic (Figure 5),
then thru the adjacent right slot of Stage 2. Repeat pairs of pulls in Stage 2 using the left and
right slots on alternate pulls. Take about 5-6 seconds for each pull for a 5" long blade (1 second
or more per inch of blade). It is important not to rush the process with ceramic knives. Slow pulls
are preferable. It may require more pulls for a blade that is severely worn or chipped. The first time
you sharpen a knife it may take up to 10 pair of alternating pulls (alternating left and right slots of
Stage 2) to fully re-angle the edge of a thin blade. Thicker blades will require more pulls. After 3
pairs of pulls check to see if blade will cut paper. For those familiar with metal knife sharpening
Ceramic knives will not develop a burr. Therefore, a gradual approach of pre-sharpening
followed by testing for sharpness is the suggested method.
Some Ceramic knives can vary widely from the industry standard 30º and even vary from one
®
side of the knife to the other. The Chef'sChoice Ceramic + Steel Model 700 will sharpen to a
precise 30º and may require multiple sharpening strokes in Stage 2 to form the ideal 30º angle.
If you are sharpening an established brand name ceramic blade you will find that only a few
(2-3) pairs of alternating pulls (alternating left and right slots) will be needed in Stage 2 to
prepare it for Stage 3 Polish/Finish.

The Chef'sChoice Model 700 has been developed with an advanced and proprietary blend of
materials to complete the sharpening of both ceramic and metal knives. This final stage of sharp-
ening creates a sharper-than-factory edge unsurpassed by any other sharpener on the market.
Upon completion of sharpening in Stage 2 perform 5-7 slow even alternating pairs of pulls,
(alternating left and right slots) in Stage 3 (Figure 6) of the sharpener (take approximately
2 second per inch of blade). We suggest beginning with 5 pairs of slow (consistent speed)
