Tachi Kanna - Sole Flattening Plane

Tachi Kanna - Sole Flattening Planes

In Japan, the soles of planes are traditionally flattened with a Tachi Kanna plane. A straight and flat sole is very important to achieve the results fine wooden planes are capable of. Because of the perpendicular set of the blade, the plane is essentially a scraper. This enables the user, without fear of tear-out, to remove even the tiniest imperfections in the sole of the plane.

This plane is very versatile and can be used for many other applications, such as in place of a scraper or a scraper plane, though the blade is not dressed to have a burr. It can be useful for cleaning up imperfections left by a smoothing plane, for instance. Anyone who has struggled to smooth tear out in difficult grain, or slight tracks left in the wood, will treasure this plane.

The iron is made of a laminate, with the cutting edge of "Blue Paper Steel". This steel is perfectly suited for plane blades. We recommend that the blade be flattened and honed on a fine whetstone before use, and it may also be necessary to increase the size of the mouth, particularly in the width. The body is of fine- grained white oak.

The planes we offer are the regular straight type, with blade setted at 90° to working direction, and the "Isuka" angled type with blade setted at 83° to working direction. Because the iron of the latter is held at an angle of a few degrees, the plane has a surprisingly gentle cut. It does not suddenly grab and begin cutting across the entire width of the wood. The shaving develops first of the left side and then widens over the entire width of the blade, therefore the plane can be much more precisely guided and the cut more easily controlled. However, you can also achieve this effect by holding the entire plane a bit angled to the working direction. We stock this plane in different blade sizes.

Japanese planes are not ready for use. They require some tuning before you can start planing. Detailed instructions how to tune up a Japanese plane you find in Toshio Odate’s book: Japanese Woodworking Tools. Click on the images to see a magnified view!
