Most of you negativity on the LMF2 comes from the outdoor crowd. The blade is too thick for a lot of things. I have one and like it but the geometry of the blade is all wrong for me. It is WAY TOO HEAVY and that would be my concern for a GI. Now as a tool to take on deployment, I think I'd feel quite well equiped with one...no question about that...no question the thing is a beast that would probably take everything a GI could dish out and come back for more. If I were humping a very long way, I might find it too heavy. Having never served in the armed forces, I will ultimately have to rely on others who have had the privilege...I have not.
My understanding is that they are (or once were) rather common items in the PX. I guess where I am going is this: First up, the Army is funny about knives these days I guess. No guarantee he'll be able to carry it. Secondly, the thing is not cheap exactly...not Randall money but not cheap. There are other blades of similar construction that would probably serve him as well or better for about the same money. ESEE, Becker come to top of mind.
But it would most certainly be a very thoughtful gift and it is a very cool knife...I have one...it's my vehicle knife...right there in my toolbox everyday right with me.
