KB Knives Aero Crossbar Lock Blue Titanium Folding Knife [KB488B]

Aero — a compact crossbar folder with diagonal milling

The Aero pairs a short drop-point working blade with diagonal handle machining. Its crossbar control sits near the pivot, while the small blade and closed dimensions make the carrying format more compact than KB’s full-size crossbar models.

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

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.
