I bought this steel years ago at Dixon's Muzzleloading Shop but today was the first time I made fire with it. It was made from an old file.
I cheated a bit and used char cloth bought from an eBay vendor, but now I'm ready to make my own. The char cloth is in the Altoids tin underneath the steel, while the flint shard is laying on some unraveled jute twine from Lowe's.
I held the char cloth on top of the flint and struck it a few times with the flint. The ember took hold quickly and I quickly moved it to the bird's nest. After a little gently blowing it exploded into flame, and I hurriedly dropped it into my fire pit.
You can see where I dispose of my cigar butts and the long matches I use to light my gas grill. ;)
Now I need to make up some of my own char cloth and find some punky wood to char.
