Speed up your sharpening process! If you're fed up with spending hours trying to reintroduce a sharpenable edge to a chipped chisel or plane blade. This is the solution. It works with most bench grinders. Just position the base in front of your grinder wheel. Screw it down to lock it in place and you're ready to go. Quickly grind away the chipped edge ready for sharpening on your regular sharpening system. Just without spending hours removing all that material on a much slower water grinder or water stone setup.
