Hawk-Lock Kinetic Folder [assisted-opening system]

This design features a folding utility knife with a complex internal architecture, integrating a Hawk-lock mechanism and an assisted-opening system. Mechanical Logic: The system is centered on a power-reserve spring. Upon engaging the flipper tab, the spring begins to compress and store potential energy. Once the blade reaches a rotation angle of approximately 60 degrees, the stored tension is released, driving the blade to a fully deployed and locked position. Durability & Material Science: A key engineering consideration was the material creep common in 3D-printed polymers. To mitigate this, the internal springs are designed to remain in a low-stress state when the knife is either fully closed or fully locked. Significant deformation occurs only during the brief opening transition, ensuring long-term reliability of the printed parts. Layout: The internal systems are partitioned within the handle scales: the left side houses the Hawk-lock mechanism, while the right side contains the a
