Special Techniques of Tsunazaburo
The easy maintenance plane blade: unnecessary “ura dashi” kanna
Regular plane has legs called “ashi” on both sides.(left below: necessary “ura dashi” kanna)
On the other hand, this easy maintenance plane blade doesn’t has legs but being processed as a large R-bending from the blade steel end point(Kaisaki) to the blade edge. Therefore, it’s only needed to whet back side of the blade even when the end of the blade is abraded.
