Any knife we carry needs to be considered a 'survival' knife. For example, I live in Memphis. We are located on a faultline (New Madrid) which is way overdue for a big ole rumble. It isn't like I can carry a Junglas and a 18" machete around with me. What I can due is make sure the knives I do have on me (usually a locking folder and a SAK Camper) are taken care of and are as sharp as possible.
