The secret of sharpening
If there is a "secret" in knife sharpening, this is it: Woodworkers write and publish more about sharpening and have more sharpening toys than knife makers and collectors. To learn more about sharpening, read Woodworking books and catalogs.
SHARPENING METHODS I HAVE USED: This section moved to systems.htm
PROFESSIONAL KNIFE SHARPENERS
Although I think the Chef'sChoice 120 is as far upscale as I think any household would need, here is a listing of the professional knife sharpeners and their features:
Hantover - really just a grinder with flap wheel sander on one end and felt honing on the other. Creates convex bevel, requires skill and safety glasses. $225
Ekland - stainless steel knife guides, slow running wheels to avoid overheating, single angle, looks like the Chef'sChoice but works differently. $241
Chef'sChoice 2000 Commercial - this machine produces a double bevel edge, unlike the triple bevel produced by their home machines. $340
Hook-Eye Belt grinder - aluminum oxide belt similar to a knifemaker's belt grinder creates a flat bevel, requires skill and safety glasses. $429
Tru-Hone - 3" 220 grit counter-rotating wheels create a toothy hollow grind edge. Adjustable angle allows a three angle bevel that offsets the fragility of the small wheel hollow grind. $625 Heavy Duty $810
Friedr. Dick SM-110 - special shaped water cooled wheels, one for each side, create flat bevel. Variable angles. Counter-rotating honing wheels to remove burr. $1493 SM-111 adds adjustable honing wheels and a buffing wheel for a more refined edge. $1624
Manabo - wet honing on the inside surface of specially shaped wheels creates a strong convex edge, variable angle, should provide the best edge holding and knife life. $1965
Let's see, $1965 would buy almost 20 $100 chef's knives. If I could
charge $5 per sharpening I would have to sharpen 393 knives to break
even.... No, I don't think so.
The angles and grits on the Chef'sChoice 110 and 301 machines are as follows:
Stage 1 20 degrees 100 grit
Stage 2 22.5 degrees 200-300 grit
Stage 3 25 degrees 500-700 grit
