alt Hacker NewsDiamond grit for polishing and grinding is now a cheap commodity. In 10,000 ct. lots, I pay from 5¢/ct. to 30¢/ct. depending on specific grit properties. I haven't searched for it, but diamond sandpaper should be a thing at these prices.

> diamond sandpaper should be a thing
I wonder, do diamond abrasives create any unusual safety/environmental issues when used around the house?
I can't imagine it being any more chemically-objectionable than tungsten carbide, but the structure and behavior of dusts could be different, etc.
The answer is probably that other things are still cheaper.
Diamond abrasives are definitely a thing. But for sandpaper, you rarely need anything more than the typical ceramic or silicon carbide abrasives. They pretty much are relegated specialized tooling for polishing, cutting, or abrading ceramics, concrete, tile, etc.
