The 15-degree sharpening angle (compared to 20 to 25 degrees for a regular knife) will allow you to slice and mince without ever crushing even the most delicate ingredients, so they retain all their flavor. All KOTAI knives are forged with 440C steel, a premium steel that combines a high carbon content for hardness and edge longevity with the optimal amount of chromium to prevent oxidation. The hidden full tang – a single piece of steel running from the tip of the blade to the end of the handle – gives the knives ideal balance and exceptional durability. Beyond the aesthetic appeal, the hammering of the “Tsuchime” (槌目) blade creates small air pockets between the blade and the slices of food. This ancestral Japanese method prevents food from sticking to the blade for pleasant and quick cutting.
