Woodcraft,
I see where you are coming from now, I think. Good splitters are sort of a speciality, and I agree that many new axes are optimized for that and not much else. Of course, a little grinding and sharpening is all it takes to change that. I don't split a lot of firewood, just to be upfront about that, but I do clear trees, prune limbs, "make" posts, and cut small medium sized wood for camping, smoking/cooking food, etc. Unlike my granddaddy, I'm not taking down huge trees, especially hardwoods, for shipping.
In my post to 300 six, I talked about one use I have for axes and a thin bitted axe doing the job well. The edge is indeed a bit fragile when knife sharp, but I look at that as a compromise, as the laws of nature are immutable mostly, but a compromise worthwhile in terms of utility in some cases.
Anyway, I've never gotten the impression that 42 is peddling snake oil! I think he is simply excited about something different and has gone to some trouble to supply us with a view into his experiences with it. As before, I may have missed something.
On a lighter note, 42 is the foremost proponent of a view similar to yours when it comes to scythes. For a while he was literally the voice in the wilderness defending us pattern scythes against sometimes outrageous claims made by purveyors of European ones.
