Interesting video!
I was surprised to hear that this is not the usual and most used method of using steel and flint .
Ive always done it this way , and in fact , am having trouble with working out how not to....
Try to strike a flint onto the steel , with tinder underneath seems rather difficult???
Even with crampball mushrooms it seems easier to do it "Joseph's" way surely?!
Even my 9 year old lad can get those lit that way...
Here's a pic I took a few weeks back when we went to try out different primitive fire methods and materials ...
Cramp balls or King Alfred's cakes and flint&steel
And with quartz (instead of flint) &steel and charcloth
bullrush and clematis definitely harder to light than charcloth or (dried) crampballs, but still really easy , much easier than friction...
Anyhow
You mention the match (spunk?) are these easy to make ?
Can you put us in the right direction please , or even just a different name for it , as a Google search brings up all sorts of wrong stuff...
😒
Either way great demonstration , thank you for sharing .
