Abstract
A power tool for trimming soft materials has a power driver with a drive train engaged with a cylindrical cutter body wherein the power driver rotates the cutter body about its longitudinal axis. A plurality of mutually spaced apart cutter teeth are fixed to an exterior surface of the cutter body. The cutter teeth each have a top surface and a sidewall surface, the sidewall surface extensive between the top surface and an exterior surface of the cutter body. The top surface of each of the cutter teeth is a four-sided convex polygon and the sidewall surface includes four mutually discrete surfaces corresponding to the sides of the polygon, with each of said discrete surfaces extending between the top surface and the cutter body.
