Forget your 3.5 lb. blunderbuss axes where you pound your way through the wood. Leave those for when you chop up roots. The Estwing axe is designed more like the small axes for canoeing in Canada. The head in those is 1.25 lbs. with a wood handle which made them light enough to carry while portaging with all your other gear. They are designed to slice into the wood not break it apart.  They also would be good battle axes, I suppose.
