I've shown this before. Below, top down, is the KaBar, LMFII, RAT RC-5, and the Buck 650 Nighthawk.
I have used those knives a bit more since the picture, although the RAT RC-5 shows it the least. An older USN version of the KaBar, without the secondary bevel, was my camping knife for years. It still is a decent performer. The next one - an LMFII my son gave me for Pappy's Day a few years back - is not something I would normally buy, as I don't like serrated blades. It has the newer sheath - and seemed the easiest to dull. It came a bit rougher ground, too. The RC-5 is a dream - a .25" thick heavy duty knife of carbon steel (Like the KaBar!) - but twice the price of the others. The Buck 650 Nighthak is comfortable to use - the edge comes sharp - and stays that way. Their 420HC is really good and the hollowground slices finely better than the others.
The RC-5 would be my first choice - the Nighthawk is a close second with the KaBar nearly tied - that LMFII is a distant last place, the serrations being a waste of knife edge space, IMHO.
