I would want a Leatherman or Bear Cutlery Copy, Swiss Army knife and a Cold Steel SRK , but a fixed Blade Warthog by K Bar is a great knife as is a Becker Companion

I have more knives than I will ever use.I carry a large Cold Steel Folder everyday and a Swiss Army knife. I own Leatherman and Bear Cutlery Copies of it both good. A cold STeel SRK is a very tough knife as is a fixed blade K Bar Warthog(don't make them anymore) Becker knives are all great. His companion and combat utility knife are both excellent survival tool.Becker Necker has a slotted handle and could be made into a spear or used on an arrow in a tight. Any of these are good I have made knives from old large bastard files and saw blades (commercial blades) any of these are not pretty but like one company does it will penatrate a car door no problem.
