The visual I got from your description of a "6'6" 260 lb man with a large bladed item moving through the crowds" was priceless. I suddenly saw Rambo in an office ignoring the workers and stalking from cubicle to cubicle! gotta love that. But I understand why you wouldn't want to walk around like that. I'm pretty lucky, I work at a feed store where we sell things like that! In fact, we have a pile of tools like axes (single and double bit), shovels, saws, rope, chain, torches, and many other things that would come in really handy in a SHTF situation. It might even be better if it happened to me while at work. Most people however don't work in such a testoterone charged place. Most days I wish I didn't. But it does afford me the unique opportunity to get alot of great gear at a substantial discount.
