Vintage Knife Blackjack Classic Blades Model 1-7

Vtg Blackjack Classic 1-7 made with Carbon Steel.  Only somewhat readable stamping is the "carbon steel" on the blade. Knife is used and sharpened, has very good edge.  Handle has a wood look to it, but looks like stabalized walnut.  Handle is tight, blade is tight.  Comes in custom made leather sheath, that also shows a lot of age and wear, but no damage.
