No it doesn't? Those concave tris on the blade look more artificial than anything. A damaged blade would have like a chip missing from it, or maybe just be bent out of shape. It's not even physically possible to shape a blade that way nor is it practical because the wedge function of the ax is lost. If you try to cut a tree with an ax like that it'll leave a weird mark and won't even penetrate through the bark
The uneven tris aren't a stylistic choice, just a bug in the model or a compromise because the creator didn't know how to shape it correctly
