Stropping wheel operates in reverse direction for more efficient blade polishing and removal of burrs.
Grinds at 18˚ to 22˚ angles—the optimum angles recommended by knife manufacturers for best performance.
Compact footprint makes it easy to use on countertops, or store away in cabinets or on shelves.
