This jig is the latest addition to Wolverine’s line of fine sharpening products. The original system is used to produce consistent grinds on curved-edge tools such as turning gouges. This jig is designed to hold a plane iron or chisel for both grinding and honing without the need to remove or reposition the blade. It can be purchased as an accessory if you own the Wolverine grinding system, or as a complete package.

The jig works on electric grinders that have 6-in. and 8-in. wheels. To use it for grinding, you mount the blade on the jig and slide the assembly onto a pivoting arm. The pivoting motion allows the blade to be lowered onto the grinding wheel, to slide back and forth across the wheel, and to be lifted from the stone for inspection, all without altering its setting. The jig was easy to set up and adjust. Once set, it was easy to grind a consistent bevel. But it was not as easy to secure the blade to the jig, where Allen screws require a separate wrench.

I was not impressed with the honing-guide feature. The jig hones okay but felt heavy and awkward. It was cumbersome to move the blade over the stones and turn it for burr removal. Because the guide wheels travel on a different surface from the stone, the jig must be adjusted to maintain a consistent honing angle for stones of different thicknesses.
