Bottom line is that whatever you have is great. It may not be great for me or the next guy but it is great for you, you made it, you carry it, and you know how to use it. It is always good to hear what other people are carrying or making, but you can't really say you should carry this or you need to carry that. That's what makes it personal. I have scaled down what I carry to a SAK, flashlight, Burts Bees, and nail clippers. More of a convenience than survival. But it works for me. I think you key chain is great Jim. Keep up the good work.
