I don’t know if baby one has thought of this idea so I’m gonna post it in a few forums. I’m putting one of these in each fire kit. Eseentially a waterproof self containing guaranteed fast flame. I know, a ferro rod is guaranteed spark. But the problem is that if your injured and have to instruct someone else how to use it, that could be life threatening. Even someone who isn’t great with a ferro rod can get a fire going with this in the rain. Gear necessary: 1. Brand new Bic Lighter (standard size- the brighter color the better) $1.50 2. About 12 inches of 550 fire cord. I got my hank of 25 feet for $4.99 and have used it to make several of these and lanyards for all my firesteels. So let’s just say about $00.50 3. “Lighter leash”. Google it. It’s a Rubber or silicon keychain to hold standard bic lighters. Almost every gas station has them for about $3.00. 4. About six inches of duck tape. Mine is skin colored so it can be used as a bandage as well but this is a great multipurpose tinder options as well. Would burn for about 3 minutes when cut into shreds. Price.... no idea. Everyone has duck tape..... all in all, this is about 5.00 per kit. Much cheaper than the exotac fire sleeve and this has two types of tinder and is just as waterproof.
