Kershaw UltraTek: Compact Diamond Sharpener for Knife Precision

Keeping a blade sharp is a small habit that pays huge dividends in safety, effectiveness, and confidence on the range, in camp, or at home. A compact sharpener that travels with your gear and gets the job done quickly is worth its weight in impact — you don’t want to be caught with a dull edge when you need precision the most.

KERSHAW ULTRA-TEK

The UltraTek Blade Sharpener is the convenient way to keep your knife sharp. The UltraTek is a compact sharpening steel that lets you quickly and easily touch up the edge on your Kershaw anywhere anytime. The UltraTek handle is made of 6061T6 anodized aircraft aluminum. Stored inside the handle is a 600grit diamondcoated oval shaft. This is the perfect grit for restoring an edge that is in generally decent 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. The UltraTek requires no water or oil. Its lightweight and easy to use.

Why a dedicated compact sharpener belongs in your kit

Routine edge maintenance is about preserving function and safety. A blade that cuts as intended reduces the force required and the risk of slips. The KERSHAW ULTRA-TEK is designed for quick touch-ups — not heavy reprofiling — and its 600-grit diamond-coated shaft is ideal for restoring a worn but otherwise undamaged edge to working condition. At $19.79, it’s an affordable insurance policy for anyone who carries or uses knives regularly.

Design and materials that make a difference

The handle is crafted from 6061T6 anodized aircraft aluminum — a resilient alloy that balances strength and light weight. That choice matters when you’re packing gear: the UltraTek doesn’t significantly add to pocket or pack weight but still stands up to regular use. The shaft is a 600-grit diamond-coated oval, stored inside the handle when not in use. The oval profile gives a slightly broader contact area than a round rod, aiding consistent angle control and reducing the tendency to rock off the edge.

Portability and carry options

Its compact footprint and internal storage mean you can stash the UltraTek in an EDC pouch, tool roll, or the pocket of a backpack. For fieldcraft or everyday carry, the ability to unscrew and stow the abrasive shaft inside the handle protects both the coating and surrounding gear. For those who prioritize low bulk, this is a practical design decision.

How to use the UltraTek for reliable results

Using the UltraTek is straightforward and intuitive — exactly what you want when working in the field or at a bench. Unscrew the shaft from the handle, flip it so the abrasive end faces outward, screw it into the other end, and you’re ready. Because the shaft is diamond-coated and 600 grit, it requires no water or oil; dry stropping maintains the abrasive surface’s effectiveness. Start at the heel of the blade and draw the sharpener away from the edge with controlled strokes, keeping a consistent angle. For most touch-ups, 6–10 passes per side is plenty. Avoid aggressive pressure — let the diamond grit do the work.

Practical tips from operators

Keep the following in mind when integrating the UltraTek into regular maintenance:

• Inspect the blade before sharpening — remove burrs and metal debris after the session with a light cloth or leather strop.
• Use the UltraTek for touch-ups and on-the-go maintenance; keep a coarser stone at home for reprofiling or repairing damaged edges.
• Store the unit disassembled if you’re packing it with other metal tools to prevent contact wear on the diamond coating.

Compatibility and brand notes

Made by Kershaw, a well-known name in knives and accessories, the UltraTek is built to complement Kershaw folding and fixed blades, though its universal sharpening action works on a wide range of steels and edge geometries. The product listing notes “Model: Various,” which reflects its intended use across multiple knife types rather than being tied to one model. For owners of Kershaw knives, this is a tidy match — but take care to maintain consistent angles according to your blade’s factory bevel.

Maintenance, longevity, and value

The diamond-coated shaft is robust and requires minimal upkeep. Because it’s a 600-grit surface, it’s not engineered to remove heavy material; instead it refines and restores. The lack of required lubricants (no water or oil) simplifies field use and helps keep the handle clean. At $19.79, the UltraTek represents a low-cost, high-utility addition to any knife kit — especially for users who value quick, repeatable touch-ups rather than full edge regrinds.

For folks who demand a dependable, portable sharpening solution without added complexity, the KERSHAW ULTRA-TEK delivers.

Whether you’re maintaining an EDC folder or keeping kitchen and camp knives in top trim, this unit covers routine touch-ups at a modest price.
