Anyone tried the cheap diamond plates on Amazon or EBay? (They look like copies of the DMT Diasharp.)
Hi,
There are lots of non-trademark infringing unbranded diamond plates out there,
a whole lot of them (all?) seem to be made by "DMD" brand,
like the harbor freight diamond sharpening plates,
The thin 6.69inch/2.95inch #80-#3000 "grit" (or mesh?) ... seem like good deal at ~$3-$4 shipped
as long as you're aware of and dont mind the potential issues
the problems with these they could
take a month before they arrive using free shipping
could need returning back to seller because
come damaged or falling apart,
could be easily damaged despite using the required low pressure with them,
need straightening/flattening (the thin stuff)
need gluing to a backing/board/another thin plate to stiffen up
come too coarse and need breaking in or
zero pressure super ultra light lapping to give finer grit finish
...
unlike the harbor freight plates they have no holes
See
The Ultrasharp 300/1200 DMD 400/1200 and the DMT duosharp C/F for a baseline
A local korean/asian/japanese supermarket sells this for $20, its cheaper online and the individual plates can be found for ~$3
