ADV Tactical Brawler Custom Acid Rain – M390

With its sweeping profile, sculpted titanium handle, and signature Acid Rain anodizing, the Brawler immediately stands apart within the ADV lineup. Combined with a satin finished M390 blade and full titanium construction, this custom build delivers the substantial feel and unmistakable character that have become hallmarks of Andre de Villiers’ designs. The 4.2″ satin finished M390 blade features a high flat grind, pronounced recurve, and long fuller that give the design its distinctive profile. Measuring 0.18″ thick, the blade balances cutting performance with the robust proportions expected from the Brawler platform. The flowing blade profile transitions naturally into the sculpted handle, creating a cohesive design from pivot to tip. Deployment comes via the flipper tab and rides on a bearing-driven pivot system. The strong detent and well-balanced flipper geometry produce fast, crisp deployment with a distinctly mechanical feel that complements the Brawler’s robust construction. Lockup is handled by a titanium frame lock with a hardened lock bar insert for dependable engagement and long-term durability. An anodized titanium pocket clip with an integrated rollerball reduces friction during carry while adding another distinctive mechanical element to the knife. The Acid Rain anodized titanium handle is the defining feature of this build, displaying vivid transitions of bronze, violet, blue, and gold that make every knife unique. Matching anodized titanium hardware and backspacer continue the finish throughout the build, while the carefully contoured handle provides a natural, secure grip that remains surprisingly comfortable despite the knife’s substantial size. Measuring 9.1″ overall and weighing 7.41 ounces, the Brawler carries reassuring substance without feeling cumbersome in hand. From its crisp deployment and positive mechanical character to its sculpted ergonomics and vibrant custom finish, this is a knife that invites interaction every time it’s picked up. The combination of premium materials, distinctive finishing, and Andre de Villiers’ signature styling results in a custom build that is equally rewarding to carry, use, and appreciate.
