Abstract
A portable manual sharpener for cutting tools such as knives, scissors and the like includes a base having a first stage sharpening station which includes a stationary non-rotatable support member with an abrasive coated planar surface on opposite sides of the support member. A pair of symmetrical slots are disposed adjacent to the planar faces with a guide surface located in each slot at a predetermined angle to the planar surface. A hold down device maintains the cutting blade in contact with the guide surface as the blade is moved through the sharpening station with the cutting edge facet of the blade in sliding contact with the abrasive particles on the planar face. The base includes an area which can be conveniently hand held.
