OK

Another question about making fire

I have seen a you tube about single flints like these



These are replacements in single flint strikers , and they are a micro copy of a ferro rod.

It is too hard to hold a ingle one by fingers but the good thing is that they have a threaded head which a genious guy in you tube attached to an eye screw



and .. you can attach it to a keychain or whatever and should actually be able to hold it and use it.

I couldn't find the right size screw to attach to but in any case use it while attached to a modified striker just to see what kind of material it would produce sparks. Is it "strike anywhere" as long as it is iron or what ??

Sadly it did not strike

I used a file , knife, hacksaw .. and many other items that did in fact produce sparks with a ferro rod, but not with this baby ferro.

So, what are your thoughts ???
