Kubey KB Knives Pioneer Black DLC Titanium Folding Knife, Black DLC 20CV by Evgeniy Bulychev (KB379C)

The Kubey KB Pioneer KB379C is a darker, more technical version of Evgeniy Bulychev’s folding knife design. The blade, made of 20CV steel, and the titanium handle are finished with a black DLC coating, while the Contoured Wave Milling pattern gives the design a distinctive, three-dimensional texture.

The 85.00 mm Drop Point blade features a flat grind and a black DLC finish. The knife opens manually using the front flipper or ambidextrous thumb studs, and once open, the blade is secured by a Frame Lock.

20CV, 60–62 HRC, and vacuum-cryogenic treatment

The blade is made of 20CV steel and hardened to 60–62 HRC. Vacuum hardening combined with cryogenic treatment promotes high hardness, wear resistance, and stable material properties during long-term use.

Drop Point, flat grind, and Black DLC

The Drop Point profile ensures a well-controlled tip and a versatile edge line. The flat grind supports efficient cutting, while the black DLC coating gives the blade a uniform, technical look and complements the dark finish of the handle well.

Black DLC Titanium and Contoured Wave Milling

The handle is made of titanium and coated with black DLC. Its surface is enhanced by Contoured Wave Milling, which gives the model a distinctive rhythmic pattern and increases the texture of the grip. The titanium backspacer and clip are finished in the same black style.

Ceramic ball bearings ensure smooth blade movement, and the Frame Lock stabilizes the blade when fully open. The clip is located on the right side and operates in a tip-up configuration.
