Well I made a stupid. I was standing in my "man cave" room of the house talking to the girlfriend, trying to scrub something (sap or corrosion or something) off of my firesteel with an acetone rag. As I'm talking to her I'm seeing that the rag isn't working, so I grab the striker and start gently scraping the stuff... without putting down the acetone rag. Yea. Genius. Well the rod sparked and lit my rag, which got dropped on the carpet. I threw a towel over it and smothered it out, but still got a nice melted spot on the carpet and an unhappy little woman. So... watch those concentration lapses!!
