Along with the Cold steel Tuff-Lite, you might consider their small clip-point Voyager, 3" blade. Also, a Buck 110 or one of the better copies, I think Schrade does one, and Puma has a few similar models.
Camillus has a military version of a boy-scout style knife, (canopener, bottleopener, awl, spearpoint blade, and a strong bail) that's all stainless-steel, and is a tough and cheap workhorse.
If we are looking to equip people in general, to "sell" the populace on carrying knives, let's hold off on hawksbill or serrated blades for now, useful as we know they can be. One step at a time! SAK and Opinels are a good way to get a lot of people interested. Even a keychain SAK at least makes the point that knives are not a criminal item in and of themselves.
