Old Vintage Marbles Ideal Knife with Rare Frontier Forge Locking Sheath For Sale

Old Vintage Marbles Ideal Knife with Rare Frontier Forge Locking Sheath. I\'ve seen a few of these over the years but never been able to find out anything about the company that altered the knife and made the sheath. It has a cut out in the guard that locks it into the sheath. It\'s in good used condition and measures 9 1/8\" overall with a 5\" blade. Please view all pictures and any questions please ask prior to offerding. Also check out my other sales and when possible I can combine shipping. Thanks for looking!
