KB Knives Protocol – a technical EDC folding knife designed by Panurin Design
KB Knives Protocol Black DLC Titanium, Black DLC M390 by Panurin Design (KB419C) combines the geometric lines of the Tanto Point blade with the monolithic aesthetics of black titanium and a Black DLC coating. The Panurin Design project was created for users who expect high rigidity, precise mechanics, and distinctive, technical styling from a premium folding knife. The contoured titanium handle forms the basis of the Frame Lock, while ceramic ball bearings ensure smooth blade operation when opening via the front flipper or thumb studs.
The blade is made of Böhler M390 powder steel, which has undergone vacuum heat treatment and a cryogenic process. A hardness of 60–62 HRC promotes long-lasting sharpness, and the flat grind ensures efficient blade glide through material. A black DLC coating covers the blade, handle, backspacer, clip, and hardware, creating a cohesive aesthetic and increasing the surface’s wear resistance. The included Pouch facilitates safe storage of the folder outside the pocket.
Böhler M390 steel Tanto Point blade
The Tanto Point profile features a strong tip and a distinct break in the cutting edge, which facilitates controlled scoring, tip work, and cutting materials that require decisive blade guidance. The flat grind ensures the blade cuts smoothly through cardboard, plastics, cords, and packaging while maintaining sufficient strength behind the cutting edge. The Black DLC finish gives the surface a matte, uniform appearance and reinforces the model’s technical character.
Böhler M390 is a high-performance powder steel valued for its excellent edge retention, wear resistance, and high corrosion resistance. Vacuum heat treatment and a cryogenic process allow the material to reach its full potential with a hardness of 60–62 HRC. In practice, this steel performs well in a folding knife intended for regular EDC use, where a stable edge and reduced sharpening frequency are key.
Titanium Handle, Black DLC, and Frame Lock
The handle, made of Titanium, ensures high structural rigidity, mechanical strength, and a favorable weight-to-durability ratio. The Black DLC coating gives the surface a deep, uniform color and increases abrasion resistance. The titanium backspacer, clip, pivot, and screws feature the same finish, giving the entire knife a consistent, monochromatic look.
The Frame Lock uses a spring-loaded section of the titanium handle to stabilize the blade when open. Ceramic ball bearings ensure smooth pivot operation, and two opening methods—front flipper and thumb studs—allow you to customize the operation to your preferences. The right-hand, tip-up titanium clip allows for discreet carry in a right-hand pocket.

Frequently Asked Questions
What is the KB Knives Protocol designed for?
The Protocol is ideal as a premium EDC folder for cutting cardboard, packaging, cords, plastics, and everyday materials. The Tanto Point profile provides a strong tip and good control when scoring.
How does the Frame Lock work?
The Frame Lock uses a spring-loaded part of the titanium handle to support the blade when open. The mechanism ensures high rigidity, simple operation, and a minimal number of moving parts.
How to care for and sharpen Böhler M390 steel?
The blade should be cleaned, thoroughly dried, and periodically treated with a thin layer of oil. For sharpening Böhler M390, it is best to use diamond or CBN wheels, finishing with a fine grit.
What sharpening angle does the manufacturer recommend?
The manufacturer specifies a range of 15°–20°. A lower angle promotes a more aggressive cut, while a value closer to 20° increases the edge’s durability during heavier use.
How can the blade be opened?
The blade can be opened using front flippers or thumb studs. Ceramic ball bearings ensure smooth and consistent operation of both methods.
