Many of you are familiar with ferrocerium rods (aka ferro rods and firesteels). It is basically a rod made of a special alloy that creates a shower of hot sparks when scraped. The advantage of something like this over a lighter is that it never runs out of fuel. These have become very popular with outdoorsmen everywhere.
The Boy Scouts of America Hot Spark is essentially just a scaled down ferro rod. It is small enough to keep on your keychain but still large enough to be very functional. If you are practiced at recognizing and using natural and improvised tinders, you will have no problem starting a fire with a Hot Spark.
I have used these for years and they never let me down. I would definitely rather use a larger fire steel, but you can’t beat the convenient size of the Hot Spark. I keep one on my key chain, in my laptop case, and stashed just about everywhere else. You will never know it is there until you need it. I have also used a ranger band (just a piece of bicycle tire inner tube) to lash these to my knife sheath.
At $2.99 these are an amazing bargain. Add one to your keychain soon!
