+1 on not liking that B&C is calling their axe a "Maine Wedge". It is not a wedge pattern, it is a copy or approximation of a Maine pattern.
I also don't like that they are not making an actual wedge pattern axe, since that is my favorite pattern. And what is more frustrating is the early pictures they put out where it looked much closer to a half wedge or almost a wedge pattern axe with fully ground sides.
I don't get the trend for copying those unfinished sides either like GB does. It isn't historically accurate to Maine axes as far as I know.
All of the antique Maine pattern axes, and Wedge Pattern axes that I have seen have all been ground smooth on the sides.
Also, unless something changed, the last time I checked B&C said that they fully harden their axes. If that is still true, it means the whole axe head is hardened the same and not differentially as that article suggests.
They were using ash because it is a local material for them, but it sounds like the emerald ash borer beetle is wiping out the ash trees at a fast rate.
