hello,
to the forum Tom. I've received some flint nodules from Woody & they're awesome best of Wiltshire flint. I haven't been to Carmarthenshire for a wee while, I've got some friends who live down there. I've spent sometime travelling & walking around the area, it's a lovely part of South Wales BTW. forum member "Beermaker" made me a few awesome file steel strikers. I've used these since whilst teaching Bushcraft skills they shew sparks no problem in conjunction with flint & can be used as ferro rod strikers too.
Regards
David
