Leather sheath by Carl Colson knifemaker. William Calvin Pass from Merritt Island, Florida, started his knifemaking career at Randall Made Knives "new" shop in Orlando in 1950. After 30 years, he left Randall to go on his own and became one of the most accomplished knifemakers of his time until he passed away in 1983.
The knife appears to have never been carried. The sheath, which was made by Carl Colson, has never been carried.
