Looking at instances of longer-term survival through history, I rarely notice people limiting themselves to one tool. More appropriately, they try to have the right tool for the job at hand.
This makes me wonder why people minimize themselves to PSKs/One Knife while on Foot. While in a Vehicle of any sort land air water, You can easily find yourself without your gear. When on foot what can possibly make you lose everything? And even more specific what can make you lose everything except that one trusty big amazing knife?
Hmmm Imma start a new topic on that instead of hijacking.
