Claim:
A hand tool grinding jig for use in co-operation with grinding apparatus having a rotatable grinding wheel, the jig including in combination: a tool clamp for clamping a tool, a leg pivotally connected to the clamp about a leg pivotal axis, said leg is angularly adjustable relative to the clamp and said leg has a ball or point-type pivot point element at an end thereof remote from the clamp, at least one pivot support for location of said pivot point element adjacent to the grinding apparatus and having a pivot receiver adapted to receive said pivot point element, and said pivot support is adjustable so that the position of the pivot receiver may be adjusted relative to the face of the grinding wheel to allow the tool to be provided at a required angle relative to the grinding wheel face, said adjustment ranging from at least a first, forward position for said pivot receiver lying below said grinding wheel and between about the outer face of said grinding wheel and the center axis of rotation of said grinding wheel to a second, back position that is outboard of the leg-to-clamp pivot distance from the face of the grinding wheel.
