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 promotes high hardness, wear resistance, and stable steel properties.
Wharncliffe, flat grind, and Satin
The Wharncliffe profile offers a long, straight cutting edge and good tip control. The flat grind provides a versatile working geometry, while the satin finish highlights the clean lines of the blade.
Blue Anodized Titanium, Frame Lock, and Ceramic Bearings
The handle is made of blue-anodized titanium. The design is complemented by gray stainless steel spacer rings and a titanium clip that matches the handle’s style.
The pivot operates on ceramic ball bearings, and Frame Lock ensures the blade remains stable when open. The clip allows for tip-up mounting on either side.

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. Proper care helps maintain both the blade’s performance and the aesthetic appeal of its satin finish.
How do I sharpen the Kubey Whammy?
Ceramic and water stones, as well as guided sharpening systems, work well for sharpening. Regular touch-ups help maintain an even and effective cutting edge.
What sharpening angle should be used for the Kubey Whammy?
The recommended sharpening angle range is 15°–20°. This allows you to adjust the geometry to achieve the desired balance between cutting performance and edge durability.
How does the Frame Lock work?
The Frame Lock uses a spring-loaded section of the titanium handle as a locking element. When opened, it moves behind the blade tang and stabilizes it in the working position.
How do you maintain ceramic ball bearings?
Keep the pivot clean and regularly remove fine debris from around it. If necessary, you can use a small amount of a cleaner designed for knife mechanisms.
