This is a duplicate of a hand-wrought survival knife made by the Randall Knives Co., a maker of speciality knives of all types. One was carried as equipment on Alan Shepard's "Freedom 7" suborbital Mercury mission on May 5, 1961. On this flight, Shepard became the first American, and second human (after Yuri Gagarin), in space. The original survival knife was lost when the hatch was jettisoned after landing in the Atlantic Ocean.
W.D. Randall, Jr., gave this knife to the Smithsonian.
