KB Knives Aero Air Crossbar Lock – Blue Titanium – M390 Blade (KB488B)
The KB Knives Aero Blue Titanium (KB488B) is a premier everyday carry folder that balances high-performance "super steel" with lightweight, aerospace-grade materials. This version of the Aero Air series features a 2.91-inch drop point blade crafted from Bohler M390 stainless steel. M390 is widely regarded as one of the best all-around knife steels available today, offering extreme edge retention, high toughness, and exceptional corrosion resistance.
The handle is constructed from 6AL4V Titanium with a vibrant Blue Anodized finish. To ensure a secure grip and a refined aesthetic, the scales feature precision diagonal milling. The crossbar locking mechanism provides a rock-solid lockup and allows for safe, one-handed operation—simply pull back the bar to "drop-shut" the blade. Weighing only 2.29 oz, the KB488B is designed to be a discreet yet incredibly capable tool for any task. It comes complete with a reversible titanium pocket clip and dual thumb studs for a fully ambidextrous experience.
Note: The KB488B model specifically denotes the Blue Titanium handle paired with a Satin M390 blade.
