Redesigned for 2020 – New locking screw to lock the Gouge Jig’s rotation. This new and additional locking screw allows you to fix the Gouge Jig s rotary movement at the required location. With this new feature, it will be easier to maintain full control when sharpening carving tools, such as V-tools. The locking screw also facilitates grinding to a completely flat bevel on violin making knives and chip carving knives when using the MB-100 Multi Base and Tormek Diamond Wheels.
