I'm warming up to the idea of a bolo or khukuri but I really doubt I would spend money on one if it came up tomorrow. There was a review of some machetes used on one of the RAT training deals that was pretty good. A good machete costs 50 bucks and I can buy one anytime.
A DF or another SOD release on the other hand? Heck I would get two of each. I really wouldn't do anything but play with a sword if I was to buy one, which I won't. I'd cough up some real dough for a folder.
