When properly stored and used with an end-grain wooden cutting board, this santoku comes the closest I’ve seen of any santoku having a permanently sharp edge. Besides being a great functioning santoku, it is one of the most attractive on the market. This santoku is labeled as dishwasher-safe, but I wouldn’t risk corroding the cutting edge with dishwasher chemicals. Shun also makes a santoku with a wider blade of the same length [DM0717].
