Emergency Multi-Function Tools

I read about the famous Ka-Bar USMC Fighting Knife (pictured above) and its reputation as one of the most useful and indestructible tools a soldier could have. It can be used to hammer, pry open crates, and cut through most anything that is cuttable (sic). It is also inexpensive. I purchased mine (with serrated edge) on Amazon.com through the Ohio Knife company, which I chose because they had the lowest price at $47.99 plus $7.29 for shipping. I must also confess that I think it looked cool and I had no reason to own this except as an emergency tool to supplement my Leatherman Charge TTi Multi-Tool (on the right).
