SHOP CASE KNIVESWork Sharp Standard Assorted Replacement Belt Kit for the Ken Onion Edition is engineered for precision, durability, and consistent results. These belts aren’t just ordinary sandpaper—they’re professionally formulated and made in America by Norton, a leading abrasives manufacturer, specifically for sharpening high-strength steels.

Whether you’re restoring a damaged blade or refining a fine edge, these belts give you the control and performance you need to get the perfect edge every time.

The X4 fine belt continues the refinement, perfecting the edge for smooth, reliable cutting performance. Finally, the 6000 extra-fine belt is designed for polishing, stropping, and serrated edges, leaving blades ready for professional use or everyday tasks.
