Yeah, Cliff no doubt it's nice to be able to whittle a new handle if necessary. The only thing that would be better is to never have too.
As for splitting large pieces of wood, like you point out wedges and mauls work better for this purpose that beating up ones axe. And are the traditional way of doing this for obvious reasons. Where ones life often depended upon the serviceability of ones axe. But then this is my opinion. There are many ways of using such tools, some a good idea if Home Depot or Wal-Mart is around the corner, some not, if in the middle of the backcountry or a survival situation. The Fiskars is quite durable enough to hammer appropriate wedges, nails, etc., and split firewood. And is a whole lot easier to carry and maintain that traditional cutting tools.
As for chopping, I just haven't seen a problem with the head connection, except in the cosmetic sense. Now of course some are better at chopping the handle, etc. and abusing their tools than they are at making edge contact with the wood. But this is true of wooden axes as well. I certainly don't have this problem, but I am not Paul Bunyan either.
And I am certainly not trying to suggest the Fiskars axe is the last word on chopping tools, ergonomically, practically, or quality wise. History would indicate this is far from the case. But for the price, IMO it's impossible to beat.
Its an inexpensive tool to manufacture (once the equipment is in place), purchase and maintain, and like you point out quite durable in use.
Heck its construction more resembles something the iceman carried than a traditional axe. And its wedge shaped head, although tough, is less than ideal for some types of more precise traditional axe work. They are certainly worth consideration for anyone in need for such tools, without the means to invest in what's considered the very best of everything, and those without the need for tools to make a historic recreation of the 'alone in the woods' documentary. Which is the category in which I belong.
Maybe at some point if you can get your hands on one cheap, why don't you put it through its paces. And list its strengths and weaknesses. Cold weathers effect on the synthetic handle would be especially interesting. But since this tool was designed in Finland, I have little doubt the handle is weak in this regard.
Fiskars. IMO maximum axe, for minimum fuss.
Comparing traditional axes to the Fiskars/Gerber line is sort of like comparing the 1911 to the Glock. Not much room in the middle. Neither is perfect for everything or everybody. But within their particular limitations they will both get the job done quite nicely.
