I have 2 that I go to a 3.5# antique craftsman, and 5# council, I'll drag the council if I know I'm going to need to smear some wedges... other wise the craftsman does general duty.
The Council brand has a couple different sizes and handle lengths, they have very good steel, and hold an edge very well (they are axes so don't expect a razor sharp edge to last more then a few days...) There are some other brands going that have the straight poll, but few and far between.
Also note that an axe is not meant to be a hammer, which is why most axes do not have a square poll on them, Council is one of the few that get that they are used to beat wedges, which should be soft plastic, (them hard head wedges are hard on axes, and probably meant for the folks that like to use hammers...)
And for those of you that like to drag hammers around, this happened yesterday, (first time in over a year... but still) 1/2 mile from the crummy at the end of a long day, figured it was less work to chop it free then to walk back and forth an extra trip.
