KB Knives Sear Frame Lock Gray Titanium Folding Knife [KB457A]

Sear — a compact working blade with a metal grip

The Sear puts its cutting blade into a shorter folding package. Its compact dimensions make it a useful comparison with longer KB designs for buyers who value carrying footprint, without mistaking the small format for a separate keychain accessory.

Opening and lock operation

Part of the metal handle itself forms the locking bar. It moves behind the open blade and is pushed aside to release it, giving the mechanism a direct, exposed interface along the handle.

Steel and maintenance

S90V is a powder-metallurgy stainless steel with a high volume of hard vanadium carbides. Its emphasis is wear resistance and long edge life, so it rewards regular edge maintenance rather than waiting until the blade is fully dull.

Handle construction

Titanium provides a corrosion-resistant metal structure. Anodizing and surface machining change its appearance and contact texture; they are different treatments from adding a separate grip scale or inlay.
