298,20 €This product is intended for use only by adults with knowledge and experience in handling sharp cutting tools. Improper use of the knife can result in serious injuries. The blade is extremely sharp and can easily cut through skin and tissue; therefore, extra caution should always be exercised while cutting, and hands should be kept away from the cutting edge. To prevent the knife from slipping, it is recommended to cut on a stable, non-slip surface and avoid excessive force, which may cause uncontrolled blade movement.
Leaving the knife on the edge of a table, countertop, or in easily accessible places—especially where children are present—poses a significant safety risk. The knife should always be properly secured after use, ideally by placing it on a stable surface or storing it in designated knife blocks, protective sheaths, or magnetic strips. The knife should never be used for tasks it is not designed for, such as opening cans or prying objects, as this can damage the tool and lead to dangerous accidents.
A dull blade increases the risk of injury, as it requires more force and is more likely to slip from the material being cut. Therefore, it is essential to sharpen the knife regularly to maintain optimal sharpness. Additionally, proper cleaning and drying of the knife are necessary to prevent corrosion and bacterial growth. Periodic inspection of the handle and blade is recommended to check for cracks, chips, or looseness. If any damage is detected, the knife should be repaired or replaced immediately.
When using the knife, focus solely on the task at hand—avoid talking on the phone, watching television, or other distractions while cutting. Ensure proper lighting in the workspace for better visibility and control. Please note that some countries or regions have laws restricting the ownership and carrying of knives. Before purchasing or using this knife, verify that its use is legal in your location according to applicable regulations.
Following these safety guidelines will help ensure safe and effective knife use, minimizing the risk of accidents and extending the lifespan of the tool.
KB Knives Protocol Black DLC Titanium, Black DLC M390 by Panurin Design (KB419C) is a premium EDC titanium folder with a Tanto Point blade, Frame Lock, and black DLC coating.
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.
