I carry the REI survival matches as part of my "fire" kit in a water proof match container. Along with the included striker stips. A concern that I have is in the event the striker gets wet how badly would it be compromised. So I have taken one of the round cutting disk for metal from my Dremmel tool case and placed it in the match container. I tried it on several matches and seems to work fine. Just a little tricky because of the size of the disk.
