The GiantMouse ACE Riv Frame Lock Folding Knife in Black PVD M390 with Black Titanium Handle is a compact, character-driven EDC built around the idea that great design starts with real places and real stories. Inspired by the original Riv dive bar near Albert and M.A.C. in Lansing, this knife carries the same energy—lived-in, dependable, and full of personality that doesn’t need to announce itself to be noticed.
What began as a nod to a meaningful local spot has evolved into a purpose-built folder with its own identity. The Riv is not a scaled-down version of another design. It was created from the ground up with its own proportions, its own feel, and its own rhythm in hand. That independence shows in how naturally it carries, how confidently it cuts, and how easily it becomes part of your daily rotation.
At the core is a 2.44-inch blade crafted from Böhler M390 steel, heat treated to ~61 HRC for exceptional edge retention, corrosion resistance, and long-term durability. Finished in black PVD, the blade takes on a deep, non-reflective appearance that enhances wear resistance while giving the knife a clean, unified tactical look. Despite its compact size, the blade geometry is tuned for real work, offering precise control for everyday cutting tasks.
A smooth ball-bearing pivot system allows the blade to deploy with effortless, consistent action. Once open, a titanium frame lock engages securely, delivering strong and reliable lockup in a slim, lightweight platform. It’s a simple, proven system built for confidence under real use.
The handle is fully titanium with a matching black PVD finish, creating a sleek, monochromatic profile that feels refined yet purpose-driven. It carries light in the pocket at just 2.8 ounces, but feels solid and controlled in hand. A brass backspacer introduces a subtle contrast element, adding warmth and a touch of classic character to the otherwise modern build. A steel wire clip provides discreet, reversible carry that keeps the knife secure without adding bulk.
Designed by Vox/Ansø and manufactured by Reate Knives, the Riv reflects a shared focus on precision engineering and thoughtful design execution. Every detail is intentional, from its compact footprint to its balanced ergonomics.
The ACE Riv Black PVD M390 is a refined everyday carry frame lock built for reliable performance, clean styling, and a pocket-friendly size that never feels underbuilt.
