The Ultra-Tek Blade Sharpener is the convenient way to keep your Kershaw sharp. The Ultra-Tek is a compact sharpening steel that lets you quickly and easily touch up the edge on your Kershaw anywhere, anytime. The Ultra-Tek handle is made of 6061-T6 anodized aircraft aluminum. Stored inside the handle is a 600-grit, diamond-coated oval shaft. This is the perfect grit for restoring an edge that is in generally good shape, but is just dull. Simply unscrew the shaft from the handle interior, turn it around, and screw it on to the other end of the handle. Now the Ultra-Tek is a comfortable 9-in. length, ideal for both sharpening and realigning the edge of your Kershaw blade.
