0,00 €KB Knives Sear Black DLC Titanium, Satin S90V Folding Knife by Paddy's Knives (KB457C)
The KB Knives Sear KB457C is a compact titanium folding knife designed by Paddy's Knives, featuring a Crucible CPM S90V blade paired with a black DLC handle and fine Micro Milling. The design features a Frame Lock, ceramic ball bearings, and two manual opening methods, resulting in a lightweight and refined EDC knife.
The 76.00 mm blade features a Drop Point profile, a flat grind, and a Belt Satin finish. It opens manually using thumb studs on both sides or a hole in the blade, and once fully extended, the blade is secured by the Frame Lock.
Crucible CPM S90V and Vacuum-Cryogenic Heat Treatment
The blade is made of Crucible CPM S90V 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 Belt Satin
The Drop Point profile provides a versatile geometry with a well-controlled tip and a functional cutting edge. The flat grind ensures smooth blade guidance through the material, while the Belt Satin finish gives the blade a refined, satin appearance.
Black DLC Titanium, Micro Milling, and Frame Lock
The handle is made of titanium and coated with black DLC. Its surface features Micro Milling, which emphasizes the technical character of the model and adds texture to the grip.
The titanium backspacer, clip, pivot cap, pins, and screws all feature a consistent black DLC finish. Ceramic ball bearings ensure smooth blade movement, while the Frame Lock uses the titanium body as the locking element. The clip is positioned on the right side in a tip-up configuration.

Frequently Asked Questions
How do I care for Crucible CPM S90V steel?
It’s a good idea to clean the blade regularly and dry it thoroughly. CPM S90V is highly resistant to wear and tear, so with proper care, it will retain its performance characteristics for a long time.
How do I sharpen the KB Sear?
High-performance abrasives, especially diamond ones, work best with CPM S90V steel. Due to its high wear resistance, sharpening may take longer than with simpler knife steels.
What sharpening angle should be used for the KB Sear?
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 as a locking element to secure the blade once it is open. 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.
