You've reminded me that it's time to do a batch of charcloth.if I pan the camera around you would see around 200kg or more of quartzite and various other stones spalled up for sparking. I never want to be without viable stone mate
I practice a LOT, every day with flint and steel, plus demos and doing my forging and youtube so I do burn through a lot of stone. Flint and steel is my passion, when I want to relax I spark steel against stone. AS I said above while I have a lot of stone on hand I am always on the lookout for more.200kg sounds like a lot, but how long would it actually last you?
