The jig (1) comprises an upper base with a lower clamp and two locking knobs for fixing the tool. The jig slides on the Universal Support on nylon bushings across the grindstone. The edge angle is set with the Micro Adjust (4) on the Universal Support (5).
There are two safety stops to prevent the tool from slipping off the stone when grinding. One inner stop (2) to be positioned according to the width of the tool and one outer stop (3) mounted on the end of the Universal Support.
The lower clamp has a ridge in the centre enabling shorter tools with a tapered shank to be firmly mounted, e.g. Japanese chisels. The upper base, which lines up the tool, is designed so the clamping pressure is distributed to the ends and the tool mounts firmly without a heavy tightening of the knobs.
The jig is designed for grinding towards the edge with the Universal Support placed vertically and for honing away from the edge with the Universal Support placed horizontally.
