The GiantMouse ACE Elmer OTS Auto in stonewash Magnacut with a blue aluminum handle represents a milestone for GiantMouse as its first automatic knife, produced in collaboration with ProTech in the USA. This is a tool built with intent from the ground up, combining GiantMouse design language with ProTech’s proven expertise in automatic knife engineering. The result is a fast, confident out-the-side automatic that feels purposeful from the first press of the button.
Some knives are defined by performance alone. Others carry something deeper. The ACE Elmer carries both, tied to a name and a story rooted in resilience and quiet strength. It honors Elmer, a WWII artillery gunner in the 36th Texas Infantry Division who fought through North Africa and Europe, from desert campaigns against Rommel to the brutal fighting at Monte Cassino and the final push toward Berlin. He returned home without fanfare, without embellishment, and simply continued forward with the same steady resolve he carried through the war. That sense of endurance is the foundation of this design.
Built by ProTech in the USA, the Elmer delivers crisp, controlled automatic action through a push-button deployment system that fires with speed and authority. The button lock is tight and dependable, giving the knife a secure feel in both open and closed positions. Every aspect of the mechanism reflects ProTech’s reputation for precision and consistency, while GiantMouse’s design influence keeps the profile clean and functional.
The blade is crafted from CPM Magnacut steel, heat-treated to approximately 62 HRC, delivering an exceptional balance of edge retention, toughness, and corrosion resistance. The stonewashed finish gives it a working character that hides wear and reduces glare, making it practical for real-world use while maintaining a refined appearance. At 3.2 inches, the blade is sized for versatility, offering control and cutting power without unnecessary bulk.
The blue aluminum handle sets this version apart with a bold yet balanced aesthetic. Lightweight and durable, it provides a solid grip while maintaining the knife’s streamlined profile. Subtle contours enhance control in hand, while the anodized finish gives it a distinct visual identity that stands out without being overstated. A milled titanium pocket clip adds strength and refinement for secure everyday carry.
At 3.2 ounces and 7.8 inches overall, the ACE Elmer is compact enough for carry yet substantial enough to perform with confidence. Limited to just 150 numbered pieces, it stands as a collector-grade release with true working capability.
