Blackjack model 4 boot knife, A-2 tool steel 3.75-inch blade, green micarta handle, original “clip-on” leather sheath. Rare UNUSED in original retail box. FREE EXPEDITED SHIPPING WITHIN THE U.S. FOR THIS ITEM.
Excellent quality original US-made Model 4 Boor Knife A-2 tool steel blade fighting knife made by Blackjack Knives. This scarce model is unused, still in the original correctly-labeled retail box with a cardboard blade protector and “clip-on” brown leather sheath. This is Model #4 of Blackjack’s Classic Blades lineup; this knife is of the highest quality. Blackjack had always made extremely well-made knives from the best materials available. But their labor intensive production also made it hard to compete with cheap mass-produced Chinese junk. This was one of the main reasons why Blackjack went bankrupt. Below is the Model 4 description:
This small combat/survival style knife balances perfectly in the hand and will take hard rugged use in any situation. The hand convex ground blade is made from solid A2 tool steel and triple tempered to 58 Rockwell C hardness. The knife is equipped with a thick aluminum alloy double quillion guard.

Blade Length: 3-3/4″ / 9.5 cm

The handle is solid, all parts are tight. Original “lip-on “boot carry” brown leather sheath is also unused; the leather is soft and supple. This well-made Blackjack model 4 boot knife in hard-to-find unused condition will be a welcome addition to any collection.
