Three key features distinguish the Chef's Choice 320 diamond electric knife sharpener:

#1: The Chef's Choice 320 knife sharpener cutting surfaces are 100% diamond-impregnated. Diamond cuts fast and smooth, is incredibly durable, and because it runs cool, the Chef's Choice 320 sharpener doesn't draw the temper from your knife's blade.

#2: The Chef's Choice 320 knife sharpener incorporates 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. The Chef's Choice 320 knife sharpener creates 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 costly damage.

This two stage sharpener incorporates 100% diamond coated disks in stage 1 and revolutionary stropping/polishing system in stage 2 to create sharp, durable edges on both straight and serrated blades. Sharpens with less material removal than conventional machines. High precision elastomeric angle guides eliminate guesswork so you get a fast, perfect edge every time. Available in choice of white, black or platinum (silver luster) finish.Two year warranty from Edgecraft, manufacturer of Chef's Choice sharpeners. Made in USA.
