The MachineWise Sonora is a purpose-driven folding knife built to be carried, used, and trusted. Designed with the mechanical soul of a balisong and refined into a compact button-lock folder, the Sonora emphasizes function, balance, and long-term reliability.
This Serial #1662 example features a 3.35-inch CPM S90V blade with a stonewash finish, offering excellent edge retention and a clean, working aesthetic. Each blade is individually heat-treated and tested prior to assembly, ensuring consistent performance and quality control.
The integral Grade 5 titanium handle is finished in Plum titanium with a distressed treatment, paired with a diamond texture for enhanced grip and tactile feedback. A contrasting brass bolster adds visual depth and reinforces the knife’s premium, tool-forward design.
A precision bushing pivot system with hardened stainless steel washers delivers smooth, controlled action, while the button lock provides secure, intuitive operation. Finished with a deep-carry pocket clip reversible for left-handed users, the Sonora is compact, capable, and built to earn its place in your pocket.
Named after the desert MachineWise calls home, Sonora marks the beginning of a new chapter—designed not for a market, but for real use.
