Michael,
It looks like the last knife you added is a Ka-Bar D2 Extreme. I have one of those. It is a well executed knife at its pricepoint but, I like a more traditional grip. The whole grip area is very round with part by the guard being very small and swelling back into your palm.
I certainly like a palm swell but, not to this extreme and not in a totally circular format.
I should also note, that the Newt Livesay knife (as pictured) has one of the most comfortable hard use grips I have personally thrashed. It certainly isn't the only good grip I have used but, I picked my knife up second hand because I just wasn't worth the price to me at retail at the time. That knife has taught me a new respect for good ole' 1095, proper heat treat and, great execution. Newt's sheaths still seem a little rough/crude but, they are certainly functional, durable and, appropriate for the primary intended consumer/market. In all fairness, I have gotten spoiled by the excellant sheaths made by custom knifemakers and/or their sheath makers and highly levels of fit and finish they provide.
If you want something to bash in the woods - Newt Livesay. If you want something that will perform better at more delicated cutting chores - Dozier. One is more of a hard use military support knife, the other is a hunting and camping knife. Both will perform well in the other role but, that is not what they were originally designed for.
