Because Spyderco's bench stones are flat and broad they are highly effective for honing wide tools like plane irons, chisels, large blades, woodworking equipment, even ski edges. As with all of Spyderco's ceramic stones, use bench stones dry without lubricants or oils. Length: 2" x 8" Ultra Fine Grit. Storage Case: Rigid Polymer with non-skid rubber feet for tabletop use.
