That thing looks like it has a secondary bevel on the edge...
That would tend to destroy its efficiency when chopping.

WAY too heavy too...
Take a look at the little Bark River mini-axe... http://www.barkriverknifetool.com/biggame/mini-axe.html
It is TINY

But it is capable of BIG jobs...
It was used(with wooden wedges) to split THIS <img src="/images/graemlins/shocked.gif" alt="" />



You can read a review and the splitting story HERE.
I have one, and it is an amazing little axe.
