Tsunesaburo 60mm Miki Powder Metal HSS Smoothing Plane – Akio Uozumi
During a recent trip to Japan we visited with Akio Uozumi, a third-generation plane blade maker in the Tsunesaburo family – the best known and most respected plane makers in Japan. The family built...
The family name is a combination of the word Tsune, meaning “always,” and Saburo, the name of the original maker, Akio’s grandfather, Mr. Saburo Uozumi.
During our visit, Mr. Akio Uozumi identified some of his most popular planes and a couple of brand-new planes, all planes we thought you would like.
Powdered high-speed steel (HSS) differentiates this plane from almost all other Japanese planes. The HSS edge is bonded to a soft iron backing for use with the most difficult woods. This high-speed steel is a special formulation created by Hitachi Metals, and the skills that Tsunesaburo brings to the hardening process create nothing less than a “super” steel. Blades are extremely tough, which creates some difficulty in sharpening. To resolve this issue, Tsunesaburo modified the blade slightly to create a hollow behind the tip of the blade, so only a small area needs to be honed and flattened to keep the blade razor-sharp. The 60mm blade is housed at 40° in a Japanese White Oak body.
