The back grinding, flat grinding, back thinning, and gradual thinning processes have been significantly improved, and the steel has been refined through a unique process. This further enhances the product's feel, making it easier to sharpen, improving the durability of the sharpness, and increasing rust resistance. The back is rounded for comfortable contact with the hand, improving hand protection.
