Thread: Interesting old oilstone

Found this on a shelf in a garage, with an old can rusting on top of it. You can still see the ring. I gave it a quick clean, and a fast flatten.
A middle grit stone, I would guess in the 3-4k range? Would certainly perform better with an oil, but I dont keep any of that stuff to try it out with.
The original sticker on the end list it as a Berea Abrasives Natural oilstone, catalog no Ns 3
BA was a division of Cleveland Quarries, which still exists today, though it seems no longer producing stones as abrasives, just for building. The BA brand apparently stretched from the turn of the last century all the way up to the early 60s, so I can only speculate this to be around the 40s-late 50s bases on the font syle of the label.
Anybody with more info on these sandstone type hones, or experience honing with one, I would love to hear more.
