NOVEL SHARPENERS TO CREATE CROSS-GRIND KNIFE EDGES
摘要
A sharpener for creating cross-grind knife edges includes a nominally flat annular abrasive sharpening member which could be a ring or a disk and is rotated about its center and held against a moving knife edge facet to simultaneously and sequentially abrade the knife edge at multiple locations on the abrasive member. The disk may be slidably mounted on a shaft in opposition to a spring restraining force. The disk is nominally disposed in a vertical orientation. The sharpener may include multiple stages including a manual stage having a pair of off axis conical shaped rotatable abrasive coated disks which have abrading lines on opposing facets which are not parallel but cross and intersect in a crossing pattern at the blade edge.
