Firesteel advice

[robevs73]

Anyone know what the best Steel is to use for firesteel (strike a lite) and what Rockwell hardness?
I've made them from O1 and hardend with a blowlamp and bucket of water but I'm thinking of making some of my design to sell.

O1 works fine over heat it a bit quench in oil
Temper not needed

A good for knife HT dosmt make a good striker

old files are good you only have to harden the striking face no heed to do the whole thing I treated one the other week from carbon steel and it sparks like a grinder lol

Interestingly a freshly laser cut piece of 01 will work as is. I assume it gets a sort of flash hardening as it gets cut.

Old files are great too.
All the best
