The Kershaw Ultra-Tek is a compact diamond sharpener for touching up folding knives and other compatible cutting edges away from the workbench. Its 4″ oval sharpening shaft uses a 600-grit diamond coating suited to restoring an edge that is still in generally good condition but has become dull. For transport, the shaft unscrews and stores inside the black-anodized aluminum handle, reducing the tool to a 5″ closed length. Reversing and threading the shaft into the handle creates a 9″ sharpening tool with enough working length for steady strokes. Kershaw specifies that the Ultra-Tek requires no water or oil during use, making it easy to keep in a pack, vehicle, or tool kit.
