I'd stay away from that particular TOPS axe. If, for some reason, you want a two piece design there are better examples out there. Here's one...

William's placing the bolts in a stronger direction, the correct direction. Impacts aren't going to be putting stress on those bolts.
Another, which seems better, would be the Nemisis Knives LMAX. I don't own these, so I don't know for sure.
I'm more inclined to stay with one piece, integral, hawks. A great option in that price range are the new RMJ designed CRKT hawks. They can be had for $117 each, and they come with a kydex sheath.
