The Sharper Image Professional Knife Sharpener is a manual, three-stage sharpener that hones, sharpens and polishes kitchen knives. It handles smooth and serrated edges, including full serrations, and can hone Japanese single-bevel blades. It suits home cooks who want a fast countertop sharpener for a mixed knife drawer, but it is not for ceramic knives. Against electric sharpeners it is simpler and quieter, with less control over edge angle; against basic two-stage pull-throughs it adds a polishing stage and serrated support.

Ratings are strong overall, with buyers generally satisfied with how quickly it revives dull kitchen knives. Some note that results depend on using the right pressure and stage for each blade.
The Sharper Image Professional Knife Sharpener hones, sharpens and polishes metal kitchen knives. It works on both smooth and serrated blades. It sharpens dull and damaged blades in seconds and can sharpen the complete edge of a serrated knife.
It also hones Japanese (left-hand) single bevel blades, and it polishes and removes rust. It is made of professional-grade stainless steel.
Pressure changes the result. Press lightly when sharpening a fine blade for slicing, and press harder for a sturdy chopping blade. It is not for use with ceramic knives.
