I've had a chance to play with this axe. It really is pretty awesome IF you're splitting pine and poplar from a managed forest plot. Branches, knots, etc, rounds larger than a foot or so in diameter, hardwoods.... Good F*ing luck. Gimme the Fiskars or the Gransfors any day.
I'm most likely going to be picking up a small scale processor in the next year or two. Just trying to make a few decisions before I commit. The biggest decision is whether I'm going to do it for just myself or if I'll sell wood too. Selling presents a few bumps, but nothing horrible. I do know if I'm going to retail firewood I'm going to be investing in a heat-treating kiln as well, with EAB, DED, and the other pests, you can't be too careful.
I'm kind of partial to Cord King because I like their cutoff saw better than a chain version. They use a circular blade with carbide inserts. Less time sharpening sounds great to me. Some of the other systems are kind of nice, I guess it will just depend on how much wood I'd be dealing with. Another factor I'm considering is where/how I'll harvest. If I'm starting from standing timber and need to skid and harvest myself, I'd definitely be considering a processor with integrated skidding like Hud-Sons Badger.
