Soaking flints

[backgear]

I purchased flints at Friendship in the 70s that were packaged in baby food jars full of ATF. Still using some of them today. Can't tell any difference between them and others recently purchased from TOW.

I keep my spare bulk bags of Fuller black english fints stored on the south side of the filing cabinet to ensure they're neither too wet nor too dry.
