Vintage M-1 Orange military paratrooper automatic knife by Schrade Walden, crafted under US government contract and produced through the 1960s. Notably, these blades were utilized by various government entities, including NASA where the knives accompanied astronauts into space. Measuring 4.25 inches closed and extending to 7 3/8 inches with the clip blade, it features durable steel liners. The clip blade deploys automatically with a button press, while the hook blade requires manual opening, typically kept accessible by paratroopers for rapid emergency deployment. Marked “Schrade Walden NY USA STAINLESS,” the clip blade shows signs of sharpening and use, there is some nicking, while the hook blade operates smoothly. The vibrant orange jigged scales are in great condition. While the knife functions well and opens smoothly, it does not securely lock into position, though the safety mechanism works effectively when closed.
