0,00 €KB Knives Bluff Crossbar Flame Titanium Folding Knife, Beadblasted M390 by Garet Caronna (KB383G)
The KB Knives Bluff KB383G is a compact titanium folding knife designed by Garet Caronna, combining a Böhler M390 blade with a handle finished in a decorative “Flamed” pattern and featuring “Ripple Milling” engraving. The Drop Point profile, Crossbar Lock, and pivot mounted on phosphor bronze washers create a design focused on precise, predictable performance and comfortable handling.
The 81.00 mm blade features a flat grind and a bead-blasted finish. It opens manually using thumb studs on both sides, and once fully extended, the blade is secured by the Crossbar 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 promotes high hardness, wear resistance, and stable steel properties during regular use.
Drop Point, flat grind, and bead-blasted finish
The Drop Point profile provides a versatile geometry with a well-controlled tip and a functional edge length. The flat grind ensures smooth cutting through material, while the bead-blasted finish gives the blade a matte, subdued appearance.
Flamed Titanium, Ripple Milling, and Crossbar Lock
The handle is made of titanium and finished with the decorative Flamed pattern. Its surface is complemented by Ripple Milling, which emphasizes the model’s technical character and adds texture to the grip. The construction is completed with gray spacer sleeves, and the titanium clip features a matching Flamed finish.
Phosphor bronze washers ensure smooth pivot operation, while the Crossbar Lock stabilizes the blade when open. 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 has high corrosion resistance, but proper care helps maintain the sharpness and appearance of the surface for longer.
How do I sharpen the KB Bluff?
High-performance abrasives, especially diamond ones, work well with M390 steel. It’s best to maintain the factory edge geometry and guide the sharpener evenly along the entire length of the blade.
How does the Crossbar Lock work?
The Crossbar Lock uses a transverse locking bar that stabilizes the blade once it is open. Releasing the lock allows the knife to be folded.
How do I care for the Flamed Titanium finish?
It’s best to use a soft, slightly damp cloth for cleaning. Avoid harsh abrasives, which can alter the appearance of the decorative surface and the Ripple Milling finish.
How to maintain the pivot on phosphor bronze washers?
It’s a good idea to regularly clean the area around the pivot to remove dust and fine dirt. If necessary, you can apply a small amount of a cleaner designed for knife mechanisms.
