Abstract
A machine for testing the sharpness of knives, particularly surgical knives, in which means is provided for grasping a cylindrical rod of material such as rubber or plastic so that a free end protrudes from the grasping mechanism, and means is provided for rotating the rod. A knife blade to be tested is mounted in a pivoted fixture which carries a predetermined weight and can be positioned so that the cutting edge of the blade rests in the side of the protruding end of the cylindrical rod. When the rod is rotated, the blade cuts into the rod, and the sharpness of the blade is determined by the number of turns required to cut through the rod.
