The Oster AAA four-point wide cutter is a replacement shearing component for the 3-inch shearing head and suitable professional handpieces. Its four-point profile identifies the cutter when matching it to a comb and existing equipment.

The cutter is made from carbon steel and receives heat treatment and Oster’s Cryogen-X process before the working surfaces are hand finished.
