GiantMouse knives blend Scandinavian design principles with Italian manufacturing precision from Maniago, a historic knife-making center with over 600 years of blade crafting tradition. Founded in 2015 by Danish designers Jesper Voxnaes and Jens Ansø alongside American entrepreneur Jim Wirth, the brand delivers production folding knives and fixed blades that prioritize clean lines, thoughtful ergonomics, and reliable performance. With Jesper Voxnaes and Jim Wirth now leading the brand into 2025, GiantMouse continues to focus on creating knives that designers would carry themselves.
CPM MagnaCut and Elmax Blade Steels
GiantMouse's ACE line features CPM MagnaCut steel hardened to approximately 62 HRC, delivering edge retention and corrosion resistance for EDC folders and outdoor use. Elmax steel appears across multiple models including the ACE Grand, hardened to around 60 HRC, while select limited editions use Böhler M390 steel. Elmax, a Swedish powder steel from Uddeholm Steelworks, has been favored by Scandinavian knifemakers for its combination of wear resistance, dimensional stability, and edge holding. These steels handle daily cutting tasks while maintaining sharpness through extended use.
Framelock and Linerlock Mechanisms
GiantMouse employs titanium framelocks with ball bearing pivot systems on compact models like the GM4, creating secure lockup in slim pocket profiles. The ACE line includes linerlock designs with bearing pivots or washers, offering smooth deployment and reliable blade security. Nested linerlock construction on select models provides strength for demanding cutting tasks while maintaining easy one-handed release. Both locking systems deliver dependable performance across thumb hole, flipper, and thumb stud opening mechanisms.
Canvas Micarta and Titanium Handle Construction
Handle materials span green canvas Micarta, natural canvas Micarta, and black linen Micarta paired with titanium backspacers. Full titanium scales appear on framelock models like the ACE Bleecker, reducing weight while maintaining structural integrity. G10 handles in jade and black provide textured grip surfaces on select ACE models. Canvas Micarta develops character through use, while titanium construction keeps carry weight minimal without sacrificing durability.
ACE Production Line and Limited GM Series
The ACE line launched in 2018 to provide wider availability while maintaining GiantMouse's design standards. Popular ACE models include the Biblio, named after the Biblio bar in Brooklyn where early planning meetings occurred, alongside the Grand, Iona V2, Tribeca, and Riv. Limited GM series knives release in runs of 400 pieces—300 standard versions and 100 special "pirate" editions marked with an eyepatch-wearing mouse logo. Both lines feature collaboration between Voxnaes and Ansø's distinctive design approaches.
Maniago Italy Manufacturing Standards
GiantMouse production partners in Maniago, Italy handle manufacturing to exacting quality standards, with facilities combining traditional craftsmanship with modern precision equipment. Designers remain involved throughout production, from material selection through prototype testing and quality control. This hands-on approach ensures consistency across knife lines. Models like the ACE Grand feature high saber flat grinds and pronounced swedges, providing cutting efficiency without sacrificing tip strength. Ball bearing pivots and proper heat treatment deliver smooth action and long-term reliability.
