Block sharpener✓

As the manufacturer and inventor of the Block knife sharpener, our product is designed to hone blades back to their original sharpness. Our sharpeners feature a patented flex design in the handle, allowing the honing rods to adapt to various knife edges. You can use them to sharpen kitchen knives, pocketknives, hunting knives, hatchets, swords, and machetes. Block sharpeners are effective on convex edges, hollow grinds, and V-blades ranging from 17 to 28 degrees, as well as any serrated edges.
