Home Forums Gear Knives and Blades Knife ID Help

So my fishing buddy Doug traded into this interesting knife. Apparently a friend of his got it at a garage sale a number of years ago and Doug who likes odd knives traded him for it. He has no idea what the heck it even is so he asked me if I knew. Well,looking at it I had no idea, other than some sort of heavy duty skinning knife maybe?? On the sheath its stamped "Sullivan" inside a Texas so maybe a Texas knife maker?? The blade itself is also stamped Sullivan. I tried my best to find something on the innernet about this "Sullivan" but no luck.

So, any ideas out there?? I know its kind of a weird thing but suppose it could be useful???

Geedubya if you see this any ideas?? I know you have seen a knife or 2

Any ideas or info would be much appreciated.
