Okay I found out a no-no, don't use sandbox sand. The first razor that I've destroyed an edge on and it was in some sandbox sand. I didn't think it was that much larger of a grit but after 14 hours the edge has too big of a chip to hone out and probably not worth taking to the water wheel.
Just a word of caution.
Good thing I didn't try gravel.
:hmmm:

ps: it was a full hollow ground and that made a difference, I'm pretty sure a wedge wouldn't have had the same results.
