The down side is that if you dont know when to stop, the edge is finished, not sharp, but kaput, destroyed, disintegrated! Thus the term "toxic". I was honing an edge after the bevel was set and wanted to see how far I could go, I was doing great but wanted just a little more so back to the stone, within about 30 seconds I noticed the slurry had turned to a steely gray with silvery specks. Whats this?! I pulled the blade from the hone, wiped it dry and got out the microscope. The edge was beyond shot, it had disintegrated, saw toothed, big chunks, little chunks, all sorts of metal missing. I had to start over.

BTW The inclusions are the color of rust, Iron would be my guess.

It reacts differently to different steels as most stones do, but with this one you had better pay significantly more attention Some steels you can finish, some had better finish on another stone.
Doesn't sound "Toxic" at all to me, looks more like you over honed and the false edge came loose an messed your edge up, if it's truly toxic you can't just hone a little and get away with it.
