This knife jig is suitable for sharpening most knife blades, larger penknives, outdoor and camping knives as well as general kitchen and chef’s knives. The design enables you to grind each side of the knife without resetting; simply flip the jig over to grind the other bevel. Set the desired bevel angle using the universal support bar. It is possible to fine-tune the bevel angle further by rotating the jig’s handle. An internal thread in the handle raises or lowers the jig in relation to the AC250WBS Wetstone Sharpening Machine’s stone.
