Poll; useful as a weapon and tool, spike is much more limited in application and is a potential danger to the wearer and those around him due to the poor sheaths common to modern tomahawks. Spike fans can always dream up handly ideas for use; as an aul, digging taters, getting it stick in someones kevlar after you use it on them, etc. A full contact blow with a hammer poll to someone would be just as deadly as from a spike, and you dont have to pull it out. As a weapon the tomahawk is neat, but in my experience I never saw the extra weight as worth the potential utility. If your vehicle mounted and weight isnt a problem then toss one in. For all the articles and discussions early on in OEF/OIF about troops carrying tomahawks, I think they are the modern version of the Confederate D guard bowie, which was hugely popular at the start of the war, but had been largely dumped by mid war due to the same weight to utility issue. I was in Desert Storm, the Balkans, and Afghanistan, and never saw anyone with a tomahawk. If someone here has a first hand carry story please post it, but please, no "my second cousin that's in SOF" stories.
