Kubey Atlas Knife Purple G10, Blackwashed 14C28N by Jelly Jerry (KU328M)

Kubey Atlas Purple G10 Folding Knife, Blackwashed 14C28N by Jelly Jerry (KU328M)

The Kubey Atlas KU328M is a high-contrast variant of the Atlas model designed by Jelly Jerry, combining a Sandvik 14C28N steel blade with a dark blackwashed finish and a purple G10 handle. The liner lock, ceramic ball bearings, flipper, and blade hole create a functional design for everyday use.

The 84.00 mm blade features a Sheepsfoot profile and a flat grind. The dark blackwashed finish gives it a utilitarian look, and the knife is opened manually using the flipper or the hole in the blade.

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 performance during regular use.

Sheepsfoot, flat grind, and Blackwashed

The Sheepsfoot profile offers well-controlled blade geometry and performs well in precision tasks. The flat grind supports efficient cutting, while the blackwashed finish minimizes the visibility of minor wear marks.

Purple G10, Liner Lock, and Black PVD Hardware

The handle is made of purple G10, which contrasts sharply with the dark blade. The design is complemented by black stainless steel spacer rings and Black PVD Hardware, creating a cohesive, dark mechanical frame.

Ceramic ball bearings ensure smooth blade movement, while the Liner Lock secures the blade when fully opened. 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 you sharpen the Kubey Atlas?

14C28N steel responds well to ceramic and water stones, as well as guided sharpening systems. Regularly refreshing the edge helps maintain good cutting performance.

What sharpening angle should be used for the Kubey Atlas?

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 uses a spring-loaded liner component that, when the knife is opened, moves behind the blade root and stabilizes the blade in the working position.

How to 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.
