If you are looking for a purpose designed general fighting/survival knife, of reasonable size, I suggest that you strongly consider a Gerber LMFII. Commercial production, good price, decent steel, reasonably HD, cut your meat, wood, cockpit canopy, hot wire, break tempered glass, hammer, etc. Built-in rough sharpener. I'd add a small nylon belt sheath to the main plastic sheath and insert a Leatherman Wave Tool, Fenix E-01 flashlight. I might add a fire steel and maybe a TOPS whistle. Thus equipped, you'd be ready for almost any emergency or camp task.
