I posted these comments on another discussion, but in the interest of getting others' views I am re-posting this here.
The Bark River customized axes do look great, and I have a Bark River Mini (customized Vaughn mini axe). Bark River does excellent work and I am a fan. However, I have to question the value of the Bark River customized Wetterlings. For camping, at least for me, I am working with dried wood for the fire. Most dried wood is hard, and some is very hard, so the axe is unlikely to sink into the wood more than an inch to 1 1/2''. So, I wonder how reprofiling the entire axe improves performance that would be useful to me. A sharp Wetterlings would serve me as well as a customized Bark River version.
For splitting, I have similar concerns. I am no expert on axe design, but have seen a number of different mauls and splitting axes, and none had thinned bits. Perhaps the Bark River Wetterlings is good for batoning, as the thinned bit may more easily work through a round, but I would not expect it to be built for splitting.
For work in green wood, I would expect improved performance (improved but not significantly), but that accounts for a small percentage of my usage.
