EXPLORER Model 11-386 folding boot knife.
"Explorer" brand owned by Guttman, one of if not the first US knife company to contract in Seki Japan in the 60's - 80's. They imported a whole bunch of models under the Explorer and Edge Mark brands including various daggers and hollow handled "survival knives". The 440 stainless is most likely AUS 6, as many US companies back then used the US equivalent for customer familiarity rather than the Japanese designation. Many of the Seki manufacturers copied other designs being produced in Seki and the US from designers like Al Mar, Gerber, Kershaw, Bob Loveless, Randall and others.
This boot knife is excellent, does not appeared to be used or sharpened. It is an attractive, well designed boot knife and would be comforting in a pants pocket, purse or backpack. It has a reassuring feel and useful design.
