KAI 関孫六 金寿 - 柳刃包丁（9.25インチ）

The blade’s extreme thinness makes slicing through raw fish feel effortless, and the edge holds up beautifully after several uses. It’s surprisingly well-balanced for its length, too.

I was nervous about handling such a long, thin blade, but the first slice through a tomato was so effortless it actually surprised me. The one-stroke cut leaves a perfectly clean edge on sashimi, and the handle feels balanced in my hand.

I've been using this for sashimi prep and the long, thin blade lets me go from heel to tip in one clean motion instead of sawing back and forth. The edge has held up well after a few weeks of nearly daily use, and it's noticeably sharper out of the box than my old knife.
