The answer is no to the PSK. I check it regularly and that's about it. My EDC on the other hand, I use virtually daily. I carry a mini PSK because I love gear. It may come in handy one day as my wife says..LOL..who knows? I also carry my larger survival bag with a more comprehensive list when we go away into the African bush (game reserves and game farms). The item I have used the most is my large Maglite torch for viewing game at night. Second is my first aid kit especially with kids around.
