Knife Sharpener Buying Guide

Sharpness plus Strength: The Chef's Choice Knife Sharpener Difference

Three key features make the Chef's Choice sharpener the World's Best diamond electric knife sharpener.

Sharpener Bevel A

Sharpener Bevel B

Sharpener Bevel C

  1. Chef's Choice knife sharpeners feature diamond-impregnated cutting surfaces. Diamond cuts fast and smooth, is incredibly durable, and because it runs cool, it doesn't draw the temper from knife edges.

  2. All Chef's Choice knife sharpener models incorporate patented guide systems. Other machines may fail to sharpen properly and can even damage your knives. The Chef's Choice knife sharpener guides produce great results every time.

  3. Most important of all is the multi-stage bevel. Conventional hollow grinding, seen in figure A, creates a weak edge that flexes (figure B) and is subject to cracking and breaking. Chef's Choice knife sharpeners create super-honed edges that are much stronger than the hollow grind because the edge has far greater support. With the Chef's Choice knife sharpener, your fine cutlery is sharpened for peak performance, and at the same time it's protected against needless damage.
