Kershaw Ultra-Tek 2535 9" Diamond Fine Blade Sharpener - Black Aluminum Handle

The Kershaw Ultra-Tek 2535 is a compact diamond blade sharpener engineered to keep pocket knives, hunting blades, and everyday-carry edges field-ready. Pulled out to its full 9-inch open length, the sharpener exposes a 600-grit diamond-coated oval shaft that quickly re-establishes a keen working edge on factory and well-used blades. The diamond rod is bonded to a lightweight oval tube and requires no water or oil to use.

The handle is machined from 6061-T6 anodized aircraft aluminum with a durable black finish, giving the Ultra-Tek a light but solid feel in the hand. When the sharpening rod is stowed, the tool collapses to a pocketable 5-inch closed length and weighs just 2.1 ounces, making it an easy addition to a pack, tackle box, or range bag.

Marked as a fine-grit sharpener in Kershaw's lineup, the Ultra-Tek is well suited to routine touch-ups on standard knife steels. To use, simply unscrew the cap, extend the diamond shaft, and draw the blade along the rod at the manufacturer's recommended angle. Compact, lightweight, and built to Kershaw's quality standard, the Ultra-Tek is a practical maintenance tool for any knife owner.
