A burnishing tool including a tapered cam shaft including a camming surfaces having a planar spatial orientation substantially the same as the planar spatial orientation of sides of a pyramid, wherein respective keys respectively extend along respective camming surfaces of the tapered cam shaft, the keys having respective longitudinal axis of extensions parallel to the respective camming surfaces and lying in respective planes normal to the planar spatial orientations of the respective camming surfaces, wherein the camming surfaces are arrayed about a cam shaft axis that is normal to a plane that is parallel to a base of the pyramid. The burnishing tool further includes a burnishing assembly, the burnishing assembly includes segmented burnishing components including respective cammed surfaces positioned on the tapered cam shaft adjacent respective camming surfaces. These segmented burnishing components include mate with the cam shaft.
