KB Knives Jarpen Crossbar Lock Blue Folding Knife [KB415E]

Jarpen — a compact blade with crossbar lock control

The Jarpen pairs a shorter working blade with an externally reached crossbar release. Its compact proportions provide a different carrying footprint from KB’s longer crossbar folders, while the opening interface remains separate from lock release.

Opening and lock operation

A transverse bar engages the blade to hold it open. Pulling the bar back releases the blade for folding; the release sits near the pivot rather than along the cutting-edge channel.

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.
