To ensure excellent sharpness and durability, Aristocut uses alloys of cobalt stainless steel, 440C stainless steel and forged Japan Premium steel. All of these alloys are among the most suitable scissor steels available and allow for the needed levels of hardness for professional hair scissors blades. The blades are convex shaped and hollow grounded - this allows for effortless razor sharp cutting. It takes about 150 steps to produce an Aristocut scissors from the blank material to the polished final scissors.
