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 ???
How fast were you striking?
How much force did you put into it?
How sharp/pointy is the file/hacksaw/knife?
Try rubbing the flint/ferrocerium on the file instead of rubbing the file on the flint
Maybe you can mount a butane/lighter wheel and use that to throw sparks
fold a piece of tin/metal around the baby ferro
punch two holes with a nail and secure the wheel in holes
then fold tin around bottom of baby ferro,
where you punch holes so screw can pass through ....
probably easier to cut down a bic/butane lighter
If you strike a butane lighter/bic, when you're its when the wheel gets up to speed that sparks
