KB Knives Nexus Frame Lock M390 Gray Folding Knife [KB442A]

Nexus — an angular tanto edge in a shaped frame

The Nexus combines a defined tanto front section with a contoured titanium grip. Its forward cutting segment meets the main edge at an angle, providing a distinct working section rather than one uninterrupted curved belly.

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

M390 is a powder-metallurgy stainless steel with high wear resistance and good corrosion resistance. Its appeal is an edge that resists abrasive wear during repeated cutting; regular light maintenance helps avoid a more demanding full resharpening.

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.
