Ek/Blackjack Model 7 boot knife bright with micarta handle. This is an original 1990's vintage John Ek Commando knife made by Blackjack Knives in Effingham, Illinois. It is from a private collection and is in factory new, unused condition with original sheath and box. Blackjack went out of business in 1997 and these knives have become very desirable and collectible, and are hard to find in this condition.
