0,00 €KB Knives Zephyr Black DLC Titanium, Black DLC M390 Folding Knife by K.C. Spiron (KB470C)
The KB Knives Zephyr KB470C is an integral titanium folding knife designed by K.C. Spiron, featuring a uniform black DLC finish. The blade, made of Böhler M390 steel, is paired with an integral titanium handle, a Frame Lock, and ceramic ball bearings, creating a compact design with a distinctly technical character.
The 94.00 mm Drop Point blade features a flat grind and a black DLC finish. It opens manually using thumb studs on both sides, and once fully extended, the blade is secured by the Frame Lock.
Böhler M390 and Vacuum-Cryogenic Hardening
The blade is made of Böhler M390 steel, hardened to 60–62 HRC. Vacuum hardening combined with cryogenic treatment promotes high hardness, wear resistance, and stable steel properties during regular use.
Drop Point, flat grind, and Black DLC
The Drop Point profile provides a versatile cutting edge and a well-controlled tip. The flat grind supports efficient cutting, while the black DLC coating gives the blade a uniform, technical look and complements the Handle’s finish well.
Integral Titanium Construction and Frame Lock
The handle is made of titanium as an integral construction, in which the rear portion of the body forms a single, continuous element of the handle instead of the classic separately mounted backspacer. The entire knife is coated with a black DLC finish, which also covers the titanium clip and hardware components, giving the model a uniform, dark appearance.
Ceramic ball bearings ensure smooth blade operation, while the Frame Lock uses the titanium body as the locking mechanism. The clip can be mounted on the right or left side in a tip-up configuration.

Frequently Asked Questions
How do I care for Böhler M390 steel?
It’s a good idea to clean the blade regularly and dry it thoroughly. M390 has high corrosion resistance, but proper care helps maintain sharpness and the surface’s appearance for longer.
How do I care for the Black DLC coating?
It’s best to use a soft cloth and mild cleaners. Avoid harsh abrasives, which can leave marks on the dark surface.
How does the Frame Lock work?
The Frame Lock uses a section of the titanium handle to lock the blade in place once it is opened. Releasing the lock allows the knife to be folded.
What does “integral handle construction” mean?
Integral construction means that the handle body and its rear section form a single, cohesive unit, without the traditional separately mounted backspacer.
How do you maintain ceramic ball bearings?
It is a good idea to regularly clean the pivot of dust and dirt. If necessary, you can use a small amount of a suitable lubricant designed for knife mechanisms.
