The Kershaw Ultra-Tek Sharpener 2535 is a portable 600-grit diamond rod that stores inside an aluminum handle for easy field maintenance.

Kershaw Ultra-Tek Sharpener Overview

The Kershaw Ultra-Tek Blade Sharpener (2535) is the ultimate field maintenance tool for keeping your edges razor-sharp anywhere. Specifically, this compact system features a 4-inch oval shaft coated in 600-grit diamond, a medium-fine abrasive that strikes the perfect balance between removing material to restore a dull edge and refining it for slicing tasks. Moreover, unlike traditional stones that require oil or water, the diamond surface works completely dry. This abrasive level is particularly effective for maintaining high-hardness steels, making it the perfect companion for the Kershaw Iridium Black Folding Knife.

Smart Storage and Handle Design

The genius of the Ultra-Tek lies in its self-contained design. The handle is machined from 6061-T6 aluminum with a black-anodized finish, providing a lightweight yet rugged casing that protects the sharpening rod when not in use. To deploy the sharpener, you simply unscrew the shaft from the handle interior, flip it around, and screw it back onto the handle, transforming the compact package into a comfortable 9-inch tool. Consequently, this design ensures the diamond surface never damages your other gear.

Practical Applications

  • Field Touch-ups: The 600-grit diamond is aggressive enough to bring a working edge back to life in seconds without removing too much steel.

  • Recurve Blades: The oval shape is perfect for sharpening knives with “S” curves or recurves (like the Kershaw Blur) that cannot be sharpened on flat bench stones.

  • Serrated Edges: While primarily for plain edges, the narrow radius of the oval rod can be used to lightly touch up larger serration scallops.

  • Dry Use: No messy honing oils or water required, making it safe to use near food prep areas or in freezing conditions.
