I meant I don't recommend hewing in the summer. It's hot.
And for axes, I've used the new Gransfors axes, and several antique axes. I much prefer the finish of a single bevel, but I'm still looking for my perfect axe (certainly not as big as NH's). There are some pretty good antique stores in Maine.
I've also veneer hewed (I call it that) a lot of timbers. I cut the square rule joinery first, then skimmed about 1/8" off with a broad axe. Still sucks real bad in the summer with no shade.
