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.

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
I now have a Tru-Hone, and while I do not like it as a major sharpener because of the dry grind and the small wheels, it does a great job of giving a toothy slicing edge to knives that have been sharpened on my wet grinder.
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
I have a SM-111, and it is the closest I have ever seen to a complete sharpening system in one unit - wet grinding, honing and polishing. It is only for knives - the scissor attachment has limited use - but can do 400 a day. Great for a big shop or knife rental service.
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
