Been using my "light my fire" firesteel for months and months, sparking it with the little piece of metal that comes with it:
One day recently I took my Mora out and instead tried to use it (I tried the spine and the edge) but I got nothing most attempts, but some times I got a couple of pathetic little sparks.
Is the reason because it's stainless steel? Or is it something else?
