0,00 €KB Knives Insomnia Flamed Titanium Folding Knife, Silver Beadblasted M390 by Panurin Design (KB441B)
KB Knives Insomnia KB441B is a titanium folding knife designed by Panurin Design, combining a Böhler M390 steel blade with a handle finished in a decorative “Flamed” style. The Tanto profile, Frame Lock, and ceramic ball bearings create a technically advanced design that offers comfortable, versatile handling.
The 88.00 mm blade features a flat grind and a silver bead-blasted finish. The knife opens manually using thumb studs on both sides or the front flipper, and once fully extended, the blade is secured by the Frame Lock.
Böhler M390 and Vacuum-Cryogenic Heat Treatment
The blade is made of Böhler M390 steel, 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.
Tanto, flat grind, and Silver Bead Blasted
The Tanto profile provides a distinctly defined tip and robust geometry at the front of the blade. The flat grind ensures smooth cutting through material, while the silver bead-blasted finish gives the blade a matte, technical look.
Flamed Titanium, Frame Lock, and Ceramic Bearings
The handle is made of titanium and finished in the decorative Flamed variant. The titanium backspacer and clip match this style, while the sandblasted hardware elements create a subtle contrast with the handle’s surface.
Ceramic ball bearings ensure smooth blade operation, while the Frame Lock uses a titanium body as the locking mechanism. The clip is positioned on the right 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 is highly corrosion-resistant, but proper care helps maintain its sharpness and surface finish for longer.
How do I sharpen the KB Insomnia?
High-performance abrasives, especially diamond-based ones, work well with M390 steel. It’s best to maintain an even edge geometry and guide the sharpener evenly along the entire length of the blade.
What sharpening angle should be used for the KB Insomnia?
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 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.
How do you maintain ceramic ball bearings?
It’s a good idea to regularly clean the area around the pivot of dust and fine debris. If necessary, you can use a small amount of a cleaner designed for knife mechanisms.
