Ok looking at ebay you can find some pretty cheap diamond plates. I found a set of three for $8. Now I know these aren't going to be high quality like atomas or DMTs but I was thinking of ordering them. I won't use for sharpening but I was thinking for slurry creation and possible flattening. Only thing I'm worried about is them being used up very quickly. I'm just wondering do these cheapos shed their grit easily? If so they won't be very good as slurry stones as it'll contaminate the waterstone. I use Sic grit on glass for flattening so they won't really be used for that. Thanks
