Abstract

See full text

A honing guide and bevel setting jig (30,40) for removable attachment to the honing guide (20) to properly position the angle and projection of a tool (22) to be sharpened in the jig to enable the tool to be honed at the proper angle and position. An adjustable roller (42) that contacts an abrasive surface (44) during use of the guide facilitates formation of micro bevels. A tool securing bar (34) having a generally triangular shape in the bar's middle section forces the arris-defining back of the tool being honed against a reference surface (24) in the guide by tightening thumb nuts (36) around threaded studs (38) projecting from the bar. Jigs for use with both square and skew edge chisel and blades are described. A concave surface clamp bar (1012) honing guide provides enhanced gripping of the tool being honed, and wedges (200) and adjustable structures expand the range of bevel angles that can be honed.
