Where to Buy

The Shun Ken Onion Chef's Knife, which is available in several blade sizes ranging from 4.5 inches to 14 inches, has an unusual design with a curiously curved spine and a wavy Damascus-patterned blade. It's named for its creator, Ken Onion, an award-winning designer of innovative knives. Most reviewers find the Shun Ken Onion Chef's Knife comfortable to hold, but some owners, particularly those with larger hands, find the ergonomic bump on the handle uncomfortable. The blade's 16-degree angle improves its sharpness but makes it more difficult for an average home user to sharpen.

Cook's Illustrated magazine includes the Shun Ken Onion Chef's Knife in a review of innovative chef's knives, and the knife is also featured in a roundup of Japanese cutlery in Bon Appétit magazine. Most owners on rate the knife highly, but a few are critical of the unusual design and cost.
