I've a couple similar to this timberline, and about all I use them for is bark shaving poles or skinning big game. The head is relatively thin and the edge is at a pretty shallow angle. In practice, they work like an Ulu with a handle. It'd be good for more intricate carving type work, but perhaps not practical at all for general timber service. You could make some dandy kindling with it, though. It would make a real nice froe on smaller pieces, but I wouldn't try driving it through anything more than 4" in diameter or you'll like peen the back of the head or the handle excessively.

As a skinning tool, I've found absolutely nothing that works better.
