Jim,
Very nice. Depending on your lifestyle and locale, you may want to consider adding a (small) compass and whistle as these go well on any keychain.

I assume that since you have a fire-starter, that these two additional components may be useful to you.

Lastly, welcome on board.

Edited Addition:
[PS - After looking at your bio information, I thank you for your service to this great country and see that my input is pretty lame for anyone of your experience level, but it maybe useful to others building keychain kits.]
