The blade dimensions are a little different. My blade is a little wider and a little longer than the AngPana blade.
I've chopped some 3" branches in half with one swing, so it chops well. As far as sharpness goes, I can hold up a sheet of paper with two fingers and make a vertical slice about 6 inches long without any tearing. I've chopped up some pallet boards and even used it to split some small pieces of firewood. It's like a hatchet, a skinning knife and a machete had a baby.
