Thin back knife

摘要

An improved cutting blade on hand-held knives. The blade is thinner at the back than it is at the cutting surface. This blade shape constitutes a knife that cuts without resistance from its sides to the material being cut. This knife gets easier to sharpen the more it is sharpened due to less stock removal the closer the edge gets to the blade back. This knife is inexpensive to manufacture. The blade stock is only as thick as the thickest point of the cutting edge. Once the blade is profiled the only stock removal is at the blade's cutting surface.
