Abstract

A knife-edge conditioning apparatus comprises at least one precision angled knife guide with one face of the knife blade maintained in sustained sliding or rolling contact and which guides the elongated edge of the blade into sustained contact with the hardened surface of an object and positions the plane of the adjacent edge facet at a precise predetermined angle relative to the contact plane of the hardened surface made of a material of equal or greater hardness than the metal of the knife blade without any tendency to abrade as the blade face is moved along the guide with its elongated edge in sustained contact with the hardened surface.
