A close one for me between the Military and the Pro-Hunter, but the Pro-Hunter gets my vote. Here's why:
1) Both the Military and the Pro-Hunter have S30V blade steel, and are pretty close in blade length, but the Pro-Hunter has a little more belly, and a stronger tip profile (and is saber-flat ground vs. full-flat ground).
2) Both the Military and the Pro-Hunter have nested, steel liner-locks, w/ radius ramps & excentric pivots (to adjust for wear), but the Pro-Hunter has dual, nested steel liners, giving it a slight edge in strength, IMHO.
2) Both the Military and the Pro-Hunter have great, grippy G10 handles, with a "50/50" choil, and both have "open frame" designs for easy cleaning, but the Pro-Hunter feels a little more secure in my hands.
I own both knives, plus a couple others on the original poster's list, but IMHO, the Pro-Hunter is THE "large liner-lock" to have & use if you could only have one of the knives mentioned.
