The SpaceX DP Flipper was developed as a possible company knife for SpaceX and is being evaluated by employees at this time. Its complexity is in its simplicity. It is sleek and simple, but with a complex 6 face grind with fuller. It is a modern take on your grandfather’s pocketknife. It is a pleasure to hold and use. The Blade is CPM-S35VN high grade knife steel and the handles are textured titanium. It is 5.25 inches opened and 3.25 inches closed. Includes leather belt sheath. Excellent condition.
