Ever since watching these excellent videos on the subject I've been meaning to give this a try, fact of the matter is as mentioned in the videos you probably wouldn't cut up your clothing for use in flint and steel fire lighting if it could be helped and our ancestors had an acute awareness of the natural world and how to make fire as their very existence depended on it.
Field Preparation Of Plant Tinder For Use With Flint & Steel By Charring
No Charcloth Flint & Steel Fire Lighting
I made the trip to my fire pit down at the creek taking along some natural materials and some tins to char them in. These materials I had on hand as I tend to gather and save tinder when I find it.
The first material I tried was some punk wood, I simply placed the material on the coals and once lit took it out and placed it in an air tight tin.
I removed the burning punk from the fire with some tongs made from a branch and placed them in a tin
After placing the burning punk in the tin I covered it and I allowed it to to cool before trying to throw a spark on it. After a couple of strikes it landed on a suitable spot and started to ember up.
