Benchmade AFO II
I have the tanto partially serrated version with black coated blade. It has been through heck and all types of weather and has never let me down. I find the strike pommel to be INCREDIBLY useful for tasks you wouldn't want to subject your blade to.
IMO, the AFO II is worth every penny of its MSRP price, but you can always find a deal if you look hard enough!
Just my $0.02
