Sandvik 14C28N and Vacuum-Cryogenic Heat Treatment
The blade is made of Sandvik 14C28N steel, hardened to 60–62 HRC. Vacuum hardening combined with cryogenic treatment was used, which promotes high hardness, wear resistance, and stable steel properties during regular use.
Sheepsfoot, flat grind, and Satin
The Sheepsfoot profile ensures well-controlled blade geometry and performs well in precision tasks. The flat grind facilitates smooth gliding of the blade through material, while the satin finish gives the blade a subdued, classic look.
Black G10, Liner Lock, and Ceramic Ball Bearings
The handle is made of black G10. The design is complemented by gray stainless steel spacer sleeves and sandblasted steel structural components.
Ceramic ball bearings ensure smooth blade operation, while the Liner Lock stabilizes the blade when fully open. The steel clip can be mounted on the right or left side in a tip-up configuration.

Frequently Asked Questions
How do I care for Sandvik 14C28N steel?
It’s a good idea to clean the blade regularly and dry it thoroughly. 14C28N combines corrosion resistance with ease of sharpening, making it ideal for everyday use.
How do I sharpen the Kubey Boxer?
14C28N steel responds well to ceramic stones, water stones, and guided sharpening systems. It’s important to maintain a consistent angle and regularly refresh the cutting edge.
What sharpening angle should be used for the Kubey Boxer?
The recommended sharpening angle range is 15°–20°. This allows you to adjust the edge geometry to your preferred balance between cutting aggressiveness and blade durability.
How does the Liner Lock work?
The Liner Lock utilizes a spring-loaded liner element that, when the knife is opened, moves behind the blade tang and stabilizes the blade in the open position.
How do you maintain ceramic ball bearings?
It’s a good idea to regularly clean the area around the pivot of dust and fine debris. If necessary, you can use a small amount of a cleaner designed for knife mechanisms.
