The Kubey Flash KU158L is a clearly utilitarian folding knife, combining a San Mai M2 blade with a green G10 handle. The Reverse Tanto profile, hollow grind, and Blackwashed finish create a visually aggressive configuration, while the mechanics—based on a flipper, ceramic Ball bearings, and a Liner Lock—ensure smooth, manual opening.
The 98.00 mm blade utilizes a San Mai layered construction with an M2 steel core and has been hardened to 60–62 HRC using the Vacuum & Cryogenic process. This combination emphasizes the model’s technical nature and aligns well with its purpose as a sturdy EDC folder.
San Mai M2 and Vacuum & Cryogenic Hardening
The blade is constructed using the San Mai construction with an M2 steel core. A hardness of 60–62 HRC was achieved using Vacuum & Cryogenic hardening, which ensures high wear resistance and cutting edge stability during regular use.
Reverse Tanto, hollow grind, and Blackwashed
The Reverse Tanto profile provides a strong, precise tip and a distinctly functional edge line. The hollow grind facilitates smooth cutting, while the Blackwashed finish gives the blade a more rugged, technical look.
Green G10, Liner Lock, and Ceramic Bearings
The handle is made of green G10, a material prized for its moisture resistance and secure grip. The design is complemented by black-finished steel spacer sleeves, a reversible clip, and ceramic ball bearings. Once opened, the blade is stabilized by the Liner Lock.

Frequently Asked Questions
How do I care for the San Mai M2 blade?
After use, it is recommended to thoroughly clean and dry the blade. Regular care helps maintain the condition of the edge and the layered structure of the San Mai blade.
How do I sharpen the Kubey Flash KU158L?
It’s best to maintain the factory edge geometry and apply the abrasive evenly along the entire length of the blade. With a hardness of 60–62 HRC, high-performance sharpening systems work well.
How does the Liner Lock work?
The Liner Lock uses a spring-loaded liner element that, when the knife is opened, slides behind the blade and stabilizes the blade in the open position.
How do you clean a G10 handle?
The handle can be cleaned with a soft brush and mild detergent. After cleaning, be sure to thoroughly dry all parts of the handle.
How do you care for ceramic ball bearings?
It’s a good idea to regularly clean the area around the pivot to remove dust and fine debris. If necessary, you can use a small amount of a cleaner designed for knife mechanisms.
