Hi Barry!
Welcome to the Knife Network!
Judging by the blade profile and the "L S" stamped on the back of the sheath, I believe that this knife was made by Randall for artists Leonard Leibowitz and his wife Shelley Shaw to be used as a "canvas " for embellishment. See an example of their outstanding work here:

Obviously this knife was never worked on by the couple. However, it makes for an interesting piece.
Cheers
David
