The GiantMouse ACE Riv is a folding knife that marries form, function, and a touch of nostalgia. Crafted with the same meticulous care and attention to detail that has become synonymous with the GiantMouse brand, the new ACE Riv in Brass is a game-changer. Departing from the framelock design, this edition embraces the liner lock, offering enhanced accessibility and a more seamless style with scales adorning both sides. Named after the historic local dive bar in East Lansing, Michigan that our CEO used to frequent in the 80's, the Riv promises to be more than just a knife; it's a compact, dependable tool. Note: The brass scales on this knife will patina over time and some oxidation may already have occurred while the knife is in the box. We try to eliminate as much plastic from our packaging as possible and the cotton bags we use instead are not airtight. When brass gets in contact with air, oxidation will happen and patina on the metals surface starts to happen.
