Great post Gary.
In Mr Gaddis' book he states on page 261 that "This is the little Model 6 Steak knife, described as: 4 1/4" blade of 3/16" stainless steel stock. 4 1/2" handle of genuine stag. Fitted with nickel silver hilt. Bo started making these knives back in the early 1950s, using ivory for the handles at that time. They were, and still are, made from Model 7 Fisherman-Hunter blades that have been ground similarly to the big carving knives."
