General, I have used MK2's from both makers, and continue to do so. The KA-BAR feels better in my hand, due to the thinner, more profiled grip. Both knives use 1095 steel, and are the same thickness, and pretty much the same profile, although there is a little difference at close comparison. The KA-BAR has a black epoxy paint finish, the Camillus is milspec parkerizing. Prices are pretty much the same at around 30-35 dollars here. As far as strength, durability, etc. both are probably identical, as they are contructed pretty much the same way using the same materials. For what it's worth, Camillus has made more knives for the military than anyone else, and they have excellent customer service. The current contractor for the MK2 is Ontario Knife Co. As for the D2 and the Next Generation version made by KA-BAR, I feel they are a waste of money as they really don't do anything any better from a user's standpoint. You can buy 3 or 4 of the real MK2's for the price of one of these things. With knives and other tools, you've kinda got to ask yourself, "Better than what?" I mean, if a knife does what you want it to do, and you are satisfied so far, why spend more money for something that is "better"? Just my thoughts, regards, Clayton.
