About the Shape - The cleaver, the iconic tool of a butcher. Unlike the thin, sexy Nakiri of Japan, the cleaver is a beefy blade designed for smashing through hard items, and boy does it work. 180mm is a good versatile size, especially if you have a bone-saw for larger work.
About Sakai Takayuki - Sakai Takayuki is well-known as the largest knife maker in Sakai. The company hosts a number of blacksmiths and craftsmen who work together to create a huge array of knives. Although the Sakai region traditionally specializes in single-bevel blades, Sakai Takayuki makes many different shapes.
The most famous blacksmith at the company is Itsuo Doi - they have built a factory for him to work in and produce his art. The collective is also host to the knife-sharpening Yamatsuka family.
