So I have to admit I had alot of information wrong. Going back through text messages with Grant alot of the verbiage was incorrect.
So to clarify; here's two knives similar shape. The white fossil handle was posted earlier in this thread. As confirmed by James it's called the "Appalachian Assassin" named by respect for a Mudbone blade made years ago.
The term "shovel dagger" is incorrect and is lost in translation with text messages and I apologize for the bad.
So clearly these two blades are quite different and I didn't realize that at the time.
Ace Of Spades comes to mind.
