Abstract: A surgical instrument (10) is provided that includes a handle (18) defining a longitudinal axis (20). The handle has an outer surface (22) including a plurality of longitudinal fins (24) that define a plurality of longitudinal grooves (26) therebetween. At least one of the longitudinal fins may project radially from the outer surface of the handle. A pair of the fins may project radially from the outer surface of the handle and are diametrically opposed. A pair of the fins may be opposed and disposed in a plane tangential to the outer surface of the handle. Two separate pairs of the fins can project radially from the outer surface of the handle and are diametrically disposed. The two separate pairs are offset 90° relative to the longitudinal axis. Two separate pairs of the fins can be opposed and disposed in alternate planes tangential to the outer surface of the handle.
