Just wondering has anyone ever had a stone go through their grinder or is it just one of those things Im paranoid about?
I can remember about 6 months ago I had a load of pre-roasted coffee that I found a stone in (luckily I had my old Russell Hobbs wizzy at that stage) and all it did was make a racket. I would imagine a burr grinder like the Rocky would be fairly cactus after putting a stone through it?

Lucky that my sweet spot on roast size is 800gm, much easier to inspect manually.
