A simple hand tool for shaping carbon rods into cylindrical tips about two millimetre in diameter. About 4mm of such a cylinder are great for the production of carbon films in an evaporator. The rod is inserted into the tool and rotated by hand against an adjustable tungsten carbide cutter until a cylinder of the desired length is formed.
Prior to cutting the rod with a small cylinder tip, the rods must be sharpened using an office pencil sharpener. The sharpener should be used for that purpose only. The cutting blade cuts into the side of the rotated rod and cannot cut into the end of a flat rod.
