you said you tried sand paper, well I'm not surprised it didn't work because the life bout matches are safty matches(a huge draw gack for a survival match if you ask me)<br>so thy wont work with any thing other than match stirker strip. the striker strip on the tub my look like like some kind of sand paper but I feel sure it isn't, in my survival kit I put a piece<br>striker strip from a normale box of safty matches and I've tested this and it works fine.<br>hope that helps
