Abstract: A surgical trocar has three integral single beveled blades having cutting edges which, when viewed head on, resemble a Y configuration. The distal end of each blade is formed with a leading cutting edge and a single trailing edge which define a single beveled face. The blades are arranged so that their leading edges converge to form a sharp point at the distal end of the trocar with the leading cutting edges extending proximally and radially from the point. The trocar is preferably extruded with three fins which are shifted relative to the longitudinal axis of the extrusion such that at most a first side of each fin lies along a ray from the longitudinal axis of the extrusion. Alternatively, both sides are shifted to one side of the longitudinal axis. The distal end of each fin is then ground to form a single bevel with at least a portion of the cutting edge of the beveled fin lying in a plane which includes the longitudinal axis of the extrusion and being angled proximally.
