Resurrecting this thread-
I have a white powder issue happening on six sheaths.
I have kept the sheaths in Zip-lock's with the air pushed out of them along with the specific stone for the correct sheath, etc. Why I like the Zip-lock's, it allows me to write all of the details of the knife so I can always be sure of the sheath that goes with which knife.
Some of the very long sheaths are not sealed and a couple of these also were showing some of the white powder.
It is not a mildew or humidity problem, seems to be the opposite low humidity and maybe moisture/oil in the leather wicking out of the leather? It wipes off with a little rubbing.
David what is Blackrock. Is this the issue you have had?
Want to nip this one in the bud!
