The Kubey Minor KU422A is a lightweight EDC folding knife designed by Maksim Epifantsev, featuring a San Mai blade with an M2 steel core and a black G10 handle. The design features a Crossbar Lock, phosphor bronze washers, and thumb studs on both sides.
The 80.00 mm blade features a Clip Point profile, a hollow grind, and a satin finish. Manual opening is achieved using thumb studs on both sides, and the Crossbar Lock stabilizes the blade when fully extended.
San Mai M2 and Vacuum-Cryogenic Treatment
The blade is constructed using the San Mai construction with an M2 steel core and has been hardened to 60–62 HRC. Vacuum hardening combined with cryogenic treatment was used, which helps achieve high hardness, wear resistance, and stable steel properties during regular use.
Clip Point, hollow grind, and Satin
The Clip Point profile ensures a well-controlled tip and versatile cutting geometry. The hollow grind promotes efficient cutting and allows for a thin geometry behind the cutting edge, while the satin finish gives the blade a subdued, classic look.
Black G10, Crossbar Lock, and Phosphor Bronze Washers
The handle is made of black G10. The construction is complemented by gray stainless steel spacer sleeves and sandblasted steel structural components.
The pivot operates on phosphor bronze washers, while the Crossbar Lock stabilizes the blade when 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?
After use, it is recommended to clean the blade, dry it thoroughly, and periodically apply a thin layer of a suitable protective agent. This is particularly important for the M2 steel core.
How do I sharpen the Kubey Minor?
Ceramic and water stones, as well as guided sharpening systems, work well for sharpening. It’s best to maintain the factory edge geometry and refresh it regularly.
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 once it is open. Releasing the lock allows the knife to be folded.
How do you 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 knife mechanisms.
