Well, maybe I should really offer the tool with axe blade and customized opposite side, chosen by the customer. Even a true crowbar can be crafted on it, no big deal.
Just a technical remark, I won't call it pulaski, nor a modification of it. In the link above, it says that certain Mr. Pulaski invented this tool. Sorry man, this tool can be tracked at least back to Aeneolithical age, made of copper. Can be seen as the roman "dolabra"then. I recall at least one medieval find as well, from the Slav-inhabited eastern part of today's Germany.
Anyway, that tool can be left aside for now. There were crowbars mentioned since then, that's what I ment when I suggested to make them in a smaller, backpacking size. Really not sure if that would make them sell well, as I saw several sizes of them factory-made already. IMO a handy tool is the "EOD Breacher Bar" that CountyComm sells. I made something like that for my bag kit (thicker and narrower though) and I have to say, that little tool is quite useful. Takes care of the kind of work you don't want to use your knife for (prying, digging...). But that's already made and sold by the CC, so ...
