Detailed information

Product detailed description

umebachi_ryuma_logoA special Japanese plane of smaller dimensions, called Uchimaru Kanna, for planing rounded surfaces, such as columns or legs. It has a concave body and blade shape. Kanna type planes have very simple processing. The blade is made from high-quality Japanese laminated two-layer steel and needs to be fitted into the plane body by hammer taps before first use, which also allows you to adjust the size of the shavings taken off the material. If you want to thin the shaving, just hit the body of the plane. The thickness of the shaving and the smoothness of the surface depend on the personal adjustment of the iron. Ideally, the blade should protrude 0.05 to 0.2 mm from the body of the plane.

Japanese planes, like Japanese saws, are traditionally used by pulling towards oneself. One hand should guide the plane and the other should gently push the plane towards the material.

How to Use the Japanese Plane

japonsky_hoblik_informaceHold the Kanna with both hands - one hand holds the back part of the plane with the iron and the other makes an L shape with the index finger and thumb, holding the part of the plane facing the user. With the movement of your body weight, pull the Kanna towards you with even and extended moves. There is no need to exert excessive force; the plane must work smoothly.

How to Adjust the Blade of the Japanese Plane

japonsky_hoblik_informaceWhen fitting the blade, lightly tap the top part of the iron with a hammer. The blade should protrude approximately 0.05 to 0.2 mm. When removing the blade, lightly hit the top corners of the plane body with a hammer. If the right or left side of the blade protrudes too much, lightly tap on the same side as the protruding blade.

What to Watch Out For

japonsky_hoblik_informaceAlthough the Japanese plane is not a demanding tool, for the correct functioning of the plane, keep in mind that you must plane in the direction of the wood grain and the blade must not protrude too much. Otherwise, the Japanese plane will not work well. The Japanese plane needs to be adjusted before use according to personal preferences.
