And percussion flaking andesite is not easy as most posters on here seem to think. I could probably bang a similar one out in 30-60 minutes, given the right hammer stone, but most people wouldn't have a clue how to even start.
I agree. It all appears to be hard-hammer (hammerstone) percussion flaking. For working andesite, that must have been one tough hammerstone! Looks to me like they started with a near-net-shape thin, ovoid andesite cobble -- and basically just edged it. I see no evidence of biface thinning (no flakes crossing the midline...)
Given the right materials (core-cobble and hammerstone) I could make a replica in a few minutes -- but I'd thicken up the padding I use on my "anvil leg" considerably over what I normaly use for chert...

(...and, based on prior experience knapping tough materials, I'd probably still be sore the next day...)
What are you? One of the those Biblical creationists or something? You're actually implying that intentionality = personal crafting? I'm sorry but this just doesn't pass the muster of peer review.
I suggest you missed a few key science courses in your local high school and college campus. You're not giving proper obeisance to "Time" and "Natural Forces" doing their...uh, I mean, its handiwork...uh...that's not a good word, either...uh...instead of handiwork how about this description:
Time and Natural Forces have forged ahead to scrape out yet another example of Natural Beauty as uncovered by archeologists: The appearance of a scultured axe that once again shows us the wonder of what Mother Earth's Womb contains if only we don't limit her gestation.
