The Shun Kanso 8 inch Chef's Knife has a super sharp edge. The Kanso blade looks quite different than other knife blades because of its metallurgy. The high-carbon, vanadium stainless steel in this blade provides a razor sharp edge. The crystalline structure of this special steel enables you to easily maintain this Kanso knife's sharp edge. The heritage finish of the Kanso knife blade beautifies with age and use. The tagayasan wood used for making the handle is extremely dense. It is the traditional wood used to make samurai swords. Full tang construction adds strength and improves balance. As with all Shun knives, the Kanso Chefs knife is hand crafted in Japan with careful attention to detail. It comes with a lifetime warranty from Shun.
