Most of the magneisum fire starters have a beaded chain. Go to the local hardware store and buy a hack saw blade for $1. Break it off the same length as the MFS and attach to the MFS with the chain. Teeth size of the saw blade is not particularly important but I choose the largest teeth to make generating shavings easier.<br><br>Use the teeth side of the saw blade to scrape a pile of shavings. Then you can use the smooth side of the saw blade to scrape the "flint". You will have to scrape the paint off the back edge of the saw blade to make metal to metal connection when scraping the flint. This will save your knife and ensure that the MFS is a complete kit by itself.<br><br>I also recommend you coat the MFS with fingernail polish or laquer to keep it from oxidizing. The oxygen in the air will being to oxidize the magneisum and make whiteish spots on the MFS. This will rub off on your other gear making a mess. There is enough MFS that loss of MFS through oxidation is not really a concern.<br><br>You might think about adding a bit of vaseline to the dryer lint. Dryer lint tends to burn very fast. The vaseline will act like the wax porition of a candle while the lint acts as the wick. This help the lint to burn slower and give you more time to get your spark into your tinder and fire materials. A used film canister makes a decent container for this combination. An alternate would be to use cotton balls with some vasoline. Don't compeletely soak the lint/cotton ball. The lint/cotton will catch the spark so you need some that is NOT coated with vasoline.<br><br>
