Kos, do you own a Merc-worX blade? They look like some pretty serious fighting knives right there.
A little bit of geek trivia for you guys; the knife Leon uses in Resident Evil 4 was inspired by the MercworX Sniper.
Spas-tick22, between the two knives the KABAR does seem like the much more practical choice for an outdoors/general purpose knife. For airsoft specifically, it will be much easier and more practical to carry since there are a variety of different sheaths and scabbards you can use to mount it on vests, LBV straps, ruck sack, belt, what have you. And for the price you wont cry if you lose it in the woods, the link I gave in my last reply sells the full size KABAR w/leather sheath for about $62.
