Title: Jig for use in sharpening cutting implement for use in wood turning

Abstract: A jig (10) for use in sharpening a cutting implement used in wood turning including a tubular body or housing (12) being mountable nearby a grinder. A tool holder (11) is located by and guided within the housing (12) so as to be pivotable about a longitudinal axis of the housing and slidable along that axis. Part of the tool passes through the housing (12) and holder (11), being attached to holder (11) so as to present a tip of the tool toward the grinder. The tool holder (11) further has a guide boss (14) engageable with a guide surface (13) on the housing such that throughout engagement a correlation exists between linear movement of the tool along the longitudinal axis and pivotal movement of the tool about the longitudinal axis, so as to enable a desired, controlled interaction between the tip of the tool and the grinder.
