Yes of course this is Great Advise. Though in my case I was asking as this one has spent most of several years now in its holder on the knife that is completely air/water tight due to 2 O-ring seals.
In the last 5-7 years it has probably only been pulled out < 20 times!
This was what prompted...
What is the best way to stop a fire steel from erroding.
Ok use it a lot - That is a given
Mine IS OLD and little used but it is in a double O-ring sealed holder (part of a knife).
It was not stored wet.
But it is baddly erroded!
I can't find a way to attach a photo here either !!!???
