I also keep a Hot Spark on the keyring. I pull it out every so often and test it against various tinders. My wife starts screaming about not setting everything on fire. I can not seem to get her to understand that starting a fire is not that easy.

My youngest is in Cub Scouts and he loooooves it. We ended up building a fire pit in the backyard so he and I could practice fire starting. He is not as thrilled with the Hot Spark since he has difficulty throwing sparks with it. On the other hand he really likes the Gerber Strike Force. Lots of sparks for him.

I am hoping to get a permanent match for Xmas. I got the Coleman imiatation with waxed cotton tinders. Have not put the lighter fluid in it yet but it does make enough sparks to light the tinders.
