The 15-degree sharpening angle (compared to 20-25 degrees for an ordinary knife) will allow you to slice and mince without crushing even the most delicate ingredients, so that they retain their full flavour. All KOTAI knives are forged from 440C steel, a premium steel that combines a high carbon content for hardness and edge retention with the optimum amount of chromium to prevent oxidation.
