Benchmade's axis lock folders are a good choice, the 710 or the big griptilian would probably be best for hard use in the field. I just got a 710 recently and I had no trouble opening and closing it at night in the dark with thick gloves. Unless you really pack mud into the works, an axis is about as reliable as a folder lock will get, and faster and easier to use than any auto. Any of the others would fail long before this will. The Benchmades are ambidextrous, compact, with good pocket clips, reversible for lefties, without giving up much on long, strong blades.
I recommend the Buck/Strider spearpoint rather than the tanto since it's a more general purpose blade. Definitely bombproof, although as a linerlock it is technically possible it can fail. The tang sticks out slightly above the handle, and I found I can use this to flip the blade open and locked without touching the thumbstud, and I can do it just as easily lefty as righty, even with gloves on. Very slick! The ATS-34 blade is thick, sharp, holds a great edge which I beat on thorn bushes without a nick or noticeable dulling. I was really impressed. The overall design of the knife is very similar to the Sebenza, by the way, just slightly larger: blade shape, open-back handle, old-style clip, single thumbstud. It is an
almost clumsily large package, though.
I carry a Leatherman Supertool myself. Great for fix-its, and the saw is super handy in the woods. You might not want to carry anything like my Sebenzas, given the price, but consider how much you will spend on lesser knives over the years ... a secondhand Sebbie, a good belt sheath like the TAD-OS, a wrist lanyard ... what could go wrong?
