I did it, I charred the punkwood as instructed, turning it into tinder, then using my home made steel and a pice of quartz that I collected from an old mine, made a spark, caught it with the tinder and then blew it into a flame..........and just to prove to myself that it wasn't a fluke, I did it again....and again, yep pretty happy with myself right now.
For me, I guess this is part of why I like blogging & sharing. I just love it when it all comes together.
Let this make you happier Keith, I just did the same thing yesterday, based on your instruction. Annealed a file and ground it down before rehardening, and used the charred punk and quartz also. I'm in Alaska, if that lets you know how universal the technique is. Thanks, I love the blog.
