Strider SnG or SMF. I used them both in Baghdad along with a platoon of infantry Marines and they performed fantastic from everything from opening cans of food, breaching doors, digging in hard packed soil, assisting in vehicle repairs to bloody ass hand to hand combat. We all swore by those knives they all made it back. None of them ever failed and were easy to maintain and sharpen in the field by hand.
Now back at home I'm still using mine in the woods from gutting n skinning deer to basic woodcraft chores, working outside in the garden and general household chores. It's strong as hell and light weight for it's strength. The ergonomics are superb bare handed or gloved.
I own 90% of all those others mentioned and they are fine blades but the Strider I know for fact does everything I mentioned incredibly well. Something about a knife you can actually say your life depended on and held up its end of the bargain.
