Most people go for the layered concept. I have my PSK, rucksack and then car,home,field supplies. There is always a knife of some sort on my person; legal folder about town,4" sheath knife on a neck lanyard and belt knife in the field and spare moras stashed everywhere. Ditto with lifeboat matches. All systems can fail, get lost or destroyed, including common sense and training. The more redundant I am , the less reDUMBdant I look <img src="images/graemlins/grin.gif" alt="" />
