Abstract:
A sharpener for blades with an elongated cutting edge with facets adjacent to each side of the cutting edge, comprising at least one rigid disk having an exposed abrasive coated surface and at least one flexible disk having an abrasive surface, each of said disks mounted on a shaft for rotation about a horizontal axis to move said surfaces across and away from the cutting edge when the blade is moved into contact with said surface, a blade guide surface juxtaposed each of said disks, said blade guide surfaces being at a predetermined vertical angle relative to a vertical line normal to said axis of rotation of said disks, said blade guide surfaces being in a plane which intersects said abrasive coated surface to function as an angular guide for the blade when the blade is placed against said blade guide surface to dispose the blade in contact with said abrasive coated surface, an edge stop-bar disposed forward of said abrasive surfaces and a second edge stop-bar disposed rearward of said abrasive surfaces, said edge stop-bars providing a location of contact with the blade edge as the blade moves into contact with each of said abrasive surfaces and cooperates with said angular guides to dispose the blade edge facet against said abrasive surface as the blade is moved across said rotating abrasive surface.
