GiantMouse ACE Elmer

The GiantMouse ACE Elmer draws its inspiration from a man simply known as Elmer, an artillery gunner in the 36th Infantry Division (United States) during World War II. Like many from that generation, Elmer carried himself with quiet resolve. He served through multiple invasions across Europe and North Africa and returned home with the same steady character that carried him through the war. The knife named in his honor reflects that same spirit—unassuming, dependable, and built to do its job without fanfare.

The ACE Elmer represents the first automatic knife from GiantMouse Knives, created in collaboration with Pro-Tech Knives. The design stays true to the straightforward nature of its namesake. A straight-back, almost trailing point blade made from CPM MagnaCut offers practical cutting performance, while the push-button automatic action delivers quick, reliable deployment backed by Pro-Tech’s well-known build quality.

An aluminum handle keeps the knife light and solid in hand, pairing simple materials with precise construction. Everything about the knife follows the same idea: no excess, just a tool that works when you need it.

Proudly made in America, the ACE Elmer stands as a quiet nod to Elmer himself and the steady confidence he carried through life. It’s a knife built with the same mindset—simple, capable, and ready when called upon.
