The 1/2″ x 10″ Replacement Belt Kit is for Work Sharp Combo Knife Sharpener (model WSCMB) and do not work with other Work Sharp products..
24 Pcs 1/2″ x 10″ Sanding Belts in total, including 4 pcs 80 Grits Zirconia belts, 4 pcs 120 Grits Zirconia belts, 4 pcs 240 Grits Alumina belts, 4 pcs 400 Grits Alumina belts, 4 pcs 1000 Grits silicon carbide belts and 4 pcs 1200 Grits silicon carbide belts..
As a professional sanding belt manufacturer, after hundreds of trials, we find that for a knife sharpner, the best material for coarse grit is zirconia, for medium grit is alumina and for fine grit is silicon carbide. So we provide this Replacement Belt Kit for perfect sharpening..
Precision engineered dual directional tape joints allow a smooth transition in either direction..
Anti-clogging compounds extend the lifetime of the belts..
