Annular cutting die, and method of circumferentially shaving away the surface portion of a rod

An annular cutting die for the circumferential shaving away of the surface portion of a rod passing therethrough, comprising an annular body having an outer annular tapered surface and inner annular tapered surface which converge to form an axially projecting annular cutting blade, said outer annular tapered surface having four substantially symmetrical, radially extending facets formed therein with each of the borders of each of said facets adjoining a border of the next adjacent facet of the annular cutting blade to thereby provide four axially projecting splitting edges substantially equally spaced about the annular cutting blade.

A method of circumferentially shaving away the peripheral surface portion of a rod as to form four discrete longitudinally extending shave sections, comprising providing an annular cutting die of a smaller circumference than the rod to be shaved, said cutting die comprising an annular body having an outer annular tapered surface and inner annular tapered surface which converge to form an annular cutting blade, with said outer annular tapered surface having four substantially symmetrical, radially extending facets formed therein with each of the borders of each of said facets adjoining a border of the next adjacent facet of the annular cutting blade to thereby provide four splitting edges substantially equally spaced about the annular cutting blade, and passing a rod through said die to circumferentially cut away the peripheral surface portion from around the rod passing through the annular die and split the circumferentially cut away peripheral surface portion of the rod into said four discrete longitudinally extending shave sections.
