Eclipse Morphing Fidget Knife

This design is inspired by the Fulcrum Knives Eclipse Morphing EDC Knife. 

The Eclipse features a button-lock / frame-lock–style mechanism that securely snaps into place in both the open and closed positions. This ensures the blade stays locked and won’t accidentally open while carried.

This is a fully 3D-printable, keychain-sized folding knife gadget designed for smooth action and satisfying fidgeting.
⚠️ This is a fidget/novelty item, not a functional cutting tool.
