The 64.00 mm blade features a flat grind and a dark blackwashed finish. It can be opened using the flipper, the thumb disc, or the Emerson Wave feature, which allows for a dynamic opening motion when removing the knife from your pocket.
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.
Pikal, flat grind, and Blackwashed
The Pikal profile gives the blade a distinctive, inverted geometry and a well-defined tip. The flat grind ensures smooth cutting through materials, while the blackwashed finish gives the blade a dark, utilitarian look and minimizes the visibility of minor wear marks.
Yellow Ultem, Liner Lock, and Black PVD Hardware
The handle is made of yellow Ultem and paired with Black PVD Hardware, creating a striking color contrast. The design is complemented by a steel finger ring coated with black PVD, which enhances the grip and the model’s distinctive ergonomics.
Ceramic ball bearings ensure smooth blade movement, 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 Jaw Pikal?
14C28N steel responds well to ceramic and water-based whetstones, as well as guided sharpening systems. Due to the Pikal’s distinctive geometry, it’s best to guide the sharpener evenly and maintain the factory edge profile.

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 component that, when the knife is opened, moves behind the blade 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.
