Back in the 1960s, during the era of the Gemini and Apollo missions, NASA needed a specially-built, multi-purpose survival knife that could be utilized in the event of catastrophe. They turned to W.R. Case & Sons Cutlery Company, now known simply as Case Knives. 50+ years after Armstrong stepped foot on the moon, a new, recreated version of the Astronaut M-1 Knife complete with machete blade, saw-teeth spine and white synthetic handle is here for you to add to your NASA / Lunar collection, bug out bag, or mountaineering gear.
