I like the Benchmade Griptilian. Doug Ritter speaks well of this knife, and as we know he has his own modifications. But even unmodified, it's a good knife. Well-balanced, ergonomic, the right length for most tasks, and a good compromise between agility and robustness. It's a very good EDC knife. I can't speak to wilderness survival since I don't have experience with that.

Someone mentioned the Cold Steel Recon tanto. I have one, too, but I'm not a big fan of it. It seems good for splitting things, but it's top heavy, the blade is too thick and too long, and the hilt is nothing to write home about. I don't find the knife that maneuverable. I've seen some other Cold Steel products, and they seem to go overboard with robustness for my taste.
