The Kubey Minor KU422D is a blackout variant of the Minor model designed by Maksim Epifantsev, combining a San Mai blade with an M2 steel core and a black G10 handle. The dark blackwashed finish, Crossbar Lock, and Black PVD hardware give the knife a cohesive, technical look.
The 80.00 mm blade features a Clip Point profile and a hollow grind. Manual opening is achieved using thumb studs on both sides, and the pivot operates on phosphor bronze washers.
San Mai M2 and Vacuum-Cryogenic Treatment
The blade is constructed using the San Mai method with an M2 steel core and has been hardened to 60–62 HRC. Vacuum hardening combined with cryogenic treatment helps achieve high hardness, wear resistance, and stable steel properties during regular use.
Clip Point, hollow grind, and Blackwashed
The Clip Point profile provides good tip control and versatile cutting geometry. The hollow grind allows for a thin geometry behind the cutting edge, while the blackwashed finish gives the blade a dark, rugged look and minimizes the visibility of minor wear marks.
Black G10, Crossbar Lock, and Black PVD Hardware
The handle is made of black G10. The design is complemented by black stainless steel spacer sleeves and Black PVD Hardware, ensuring a consistent blackout aesthetic.
The pivot operates on phosphor bronze washers, while Crossbar 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 the San Mai M2 blade?
It is recommended to clean the blade regularly, dry it thoroughly, and periodically apply a thin layer of protective coating. The M2 steel core requires special attention.
How do I sharpen the Kubey Minor?
Ceramic and water stones, as well as guided sharpening systems, work well for sharpening. Regularly refreshing the edge helps maintain good cutting performance.
What sharpening angle should be used for the Kubey Minor?
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 Crossbar Lock work?
The Crossbar Lock uses a transverse locking bar that stabilizes the blade when open. Releasing the lock allows the knife to be folded.
How to maintain the pivot on phosphor bronze washers?
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 the pivot mechanism.
