Prototype replica of the Randall steel survival knife carried by Gus Grissom on his MR-4 Liberty Bell 7 mission. Crafted in 2006, the knife measures 9.5″ long and is constructed of O-1 high carbon steel with brown linen micarta grips. Includes a leather sheath. In fine condition. Accompanied by a letter of provenance from The Space Museum in Bonne Terre, MO, in part: “In 2006, The Space Museum…celebrated its grand opening. The special guest for the opening was Lowell Grissom, the younger brother of Gus Grissom. In recognition of Lowell’s help in the museum opening, a replica of the Randall knife was crafted for presentation to him; permission to create this knife was obtained from the Randall Knife Company of Orlando, FL. No makers mark has been included on the blade in deference to them. This trial knife was made prior to fabricating the presentation article. It is accurate in every way to the original…The exception to this knifes accuracy is that the blade is made of O-1 high carbon steel instead of stainless…Only two of these knives exist; this trial version and the one presented to Mr. Lowell Grissom.” Also includes two signed photos of Lowell Grissom, one of which shows him holding his example of this knife.
