You have a No. 3 Boat Knife. Grohmann has always made the knives, but most have been sold under the name of the designer, D.H. Russell, no kin of the Russell boot people.


I have a Boat Knife with black Micarta handle in a bookcase near my desk. The factory gave the blade a bright polish, on special order. They also furnished both the normal pouch sheath and the Canadian Forces military sheath, which has a flap.


RCAF planes have sometimes carried the larger No. 4 Survival knife. You can also see this knife among the safari gear in Robert C. Ruark's safari article in, Playboy from April, 1965, if I recall the right date. Your library may have it. I don't know if Ruark actually carried this knife or if a staff member assembled the gear shown at Abercrombie & Fitch, etc.


Ruark did wear and recommend the Russell's Birdshooter boots.


The S on your blade indicates Stainless. I think the Boat Knife always had stainless, which was an option with other Russell knives.
