My inexpensive nail clippers are chrome plated steel. All the keys on my key ring are brass or some other non-ferrous metal (I checked with a magnet). The nail clippers have that small nail file built in. I have read a few blog posts that talk about using a nail file as the steel for starting a fire, and I wonder if it is possible with the small nail file in the nail clippers.
We already know that the battery in my key fob is not going to work to start a fire
Can I start a fire with the file in my nail clippers?
