The sharpness of the edges of surgical incision blades is very important to control the cutting efficiency. The desired property depends mainly on the geometry of the blade and its material. Sharpness means faster cutting and higher quality. According to the principles of fracture mechanics, the blade sharpness index was introduced and after melting and alloying under vacuum and casting of amorphous alloys (Zr55Cu30Al10Ni5) 100-XNbX (X = 0,,2) in that atmosphere, grinding operation for sharpness was performed and the Its sharpness index was compared to a commercial sample of stainless steel. The present study showed that under the same conditions of blade geometry, the mentioned bulk amorphous alloys can increase the blade sharpness by up to 57% compared to commercial stainless steel blades
