Found Bob's 1980 Catalog. There are extensive pictures of his Cargill folders, most of which featured his "Sidelock" mechanism, as he called it in the catalog. Also included is a copy of the patent of the mechanism, wherein it is called a "bolster-activated lock-back knife". In the catalog Cargill states the mechanism was licensed to Jim Frost, and the patent state Mr. Frost was the assignee of the patent. Cargill also stateas that he used mostly 1095 high carbon and 440 stainless and tried to take them to between 58-60 Rockwell for what he considered optimal hardness and edge holding. There are also two pages where he talks about the Cripple Creek knives and his wrecking his body from too much production of the Cripple Creeks. A lot of pages!
