ABSTRACT:
A process for producing an endodontic instrument by selectively hacking burr-like cutting projections or barbs into an elongated metal rod. A cylindrical hacking blade or other suitable blade having a convex cutting edge is preferably used to produce generally cup-shaped or concave barbs for greater strength and cutting efficiency. The barbs may be formed in a variety of shapes, sizes, orientations and patterns, such as regular or irregular helical or linear patterns, on the instrument.
