Convex hollow ground and semi-convex ground

Yakushi shears get their sharpness from convex hollow ground or semi-convex ground blades. Whereas only the best Japanese steel can be convex ground, a semi-convex ground, which uses a bigger grinding edge, is used for all other shears.

At the same time, the concave hollow ground on the inner side ensures that the blades only touch at the point of intersection. This reduces the cutting edge resistance to a minimum and results in a smooth running shear.

Yakushi Japan stands for fatigue-proof working with highest precision.
