Yari Ganna (Yarri Kanna) - Handling Instructions

When pulling towards the body over the wood surface, fine shavings must roll off. A high sharpness of the blade and the correct posture of the tool are prerequisites. The beginner tends to hold the blade at too steep an angle to the wood surface, causing the Yarri Kanna to get stuck. Position the Yarri Kanna at as flat an angle as possible and at an angle to the pulling direction, so that it almost glides over the surface. Do not use it as a drill and do not apply excessive pressure when "planing." Due to its shape and hardness, the tool may otherwise break. We cannot provide any warranty for this.

Sharpening is overall less complicated than it may seem. If you can sharpen plane irons and knives by hand, then you have the prerequisites to learn the sharpening technique for this tool in no time. The cross-section of the blade is nothing but a triangle, consisting of the two bevels and the mirror side. The mirror side is hollow - like with Japanese chisels. For sharpening, take a small shaping stone (the sculptor's set with Japanese water stones) for the two bevels. Clamp the tool with the handle, ensuring that the underside (mirror side) is resting and that you can move this shaping stone freely over the bevels. After a certain time, two burrs will form on both sides of the mirror side. The honing, that is, the removal of the burr, now occurs by placing the mirror side firmly on a smooth honing stone and, adjusting to the curved shape of the blade, sliding back and forth on the stone.
