PURPOSE: To manually polish a cutting tool by a method wherein a pair of symmetrical slots inclined in a manner to face a polishing surface are formed at a polishing part, and a plane inclining at a prescribed inclination angle and a guide surface crossing the polishing surface are formed in each slot.
CONSTITUTION: Polishing parts 14 and 16 arranged at a base 12 are provided with a support member provided on end faces on both sides with an abrasive coated planner polishing surface. In the polishing parts 14 and 16, slots 28 and 48 formed in an symmetrical shape are arranged at the respective end faces on both sides of the support member with guide means 32 and 34 arranged at the slots 28 and 48, respectively. Guide means are provided with respective guide surfaces 32 and 34 arranged at a prescribed angle with a polishing surface. The cutting edge of a cutting tool is maintained in contact with guide surfaces 32 and 34 by a blade pressure means so that the cutting edge part of the cutting tool is slid in contact with each of polishing surfaces.
