I know this isnt a custom, but I bought it the other day at an auction, It was in a box of Misc. sanding belts I got for $5.00.
Its marked Marble's, Gladstone Mich. USA
On reverse it says Pat 1512 and L.E.A.
Any help would be apprecated.
Thanks,
Mike

If I had a pic I may be able to help more.

What I do know is that Marbles have always been top notch knives. Their old stuff was made from 1095 steel and were rugged and reliable. Their new blades are made from 52100.

Sounds to me like you got a nice knife!:)

Try the Marbles forum on Knifeforums. They shoudl definitely be able to answer your question.
