I figure the more ways I can start a fire the better chances I have. Some work better than others. I watched that survivor man episode and was excited to give it a try. I purchased mine off e bay. its plexi with an aluminum piston. took me a couple of tries to get and ember using char cloth but it works. its a very old way of fire making. problem with the wood ones i found out is that in time they can crack from drying out. i wouldn't give up my fire steel or the bic, but its a fun way to start a fire. try the coke can and chocolate. i was amazed that worked for me
