Since you mentioned lighters <img src="/images/graemlins/smile.gif" alt="" /> I'm allways trying to improve upon this subject myself my lastest addition is this:
It's a
metal case made by Bic that fits the mini Bic. I'm planing on doing a review of it soon but want to carry it a bit longer to see how it holds up. It will take care of your durability issues and has some other benefits. It features a better grip and hole for a lanyard.
