The axe in question is a little specialized so, resale will be a little difficult. Axes like that do go out of stock so, when Gransfors USA is out of stock, IF you can find someone who wants one you can make some money on it. In this tough economic climate, I personally wouldn't speculate on this axe with my hard earned money.
For a $100 I would buy it and use it. For more money, I will shop elsewhere. I love the Gransfors axes I have but, Wetterlings are a lot cheaper and give me 90% of a Gransfors (when I get the good ones and not the cheap consumer grade Wetterling models).
