Strange design... never seen anything like it. The flat blade would probably make it a good chopper, but I'm guessing it would be terrible at splitting. In terms of durability, I suppose if you understand it's limitations and don't try to do too much with it, it would be fine.
Might make a solid addition to a bugout bag as a fire prep / wood processing tool, particularly due to its weight. But I don't know if I would want to trust my life to it. And handle replacement might be a challenge. I'll just stick with my small machete.
