I got this because my old diamond plate was really starting to rust in spots. I got a cheap one and wanted to spend a bit more hoping to get better quality. I use these to lap my whetstones. After two uses is this plate, Iím noticing quite a bit of rust on both sides of the plate. I wash off all slurry and let it drip dry vertically. I contacted CKTG, hoping they could make it right for me. Mark was quick to respond to my inquiry. I was told basically this issue is very common and wonít affect performance. But I dont like rust particles flaking off into my razor hones...It looks like Iím stuck with another rusting diamond plate.
Anyway both the 400 and 1000 sides have multiple high spots that need to be knocked down if youíre using this to lap whetstones. Iit does seem to lap stones well enough.
Next time Iíll spend good money for a DMT or Atoma. Hopefully neither of those will rust on me.
It's easy to keep it from rusting. Use it with oil instead of water.
Nice diamond plate. My version seems quite flat. Much more aggressive, at least early on, than the grit rating would seem to indicate. Even the 1000 grit side was pretty coarse on the first couple of knives it was used for. Hopefully it will smooth out or will be used only to flatten water stones.
Seems flat to me,but I do not have a granite inspection plate to check it with. It works very good to flatten all my water stones. But then I tried to flatten a norton india oil stone. Even after trying many ways to clean the oil out of the stone, ( that did not work). I think the oil stone damaged the diamond plate some. Guy's I would not try to flatten a oil stone with a diamond plate. I finally got it flat by lapping it with silicon carbide grit on a flat iron plate. Latter a guy on youtube said india stones are oiled when made and can never be de-oiled, I agree. Good plate for the money, got it quick to. I am gong to order the 140.
This is very nice diamond double sided plate, its is fully flat, it cuts trough steel moderately quickly, I have just used it on 9 knives yesterday and it was used to reset and restore the knife edge on various types of knifes all western with a range of hrc's between 56-63. in every single one of them it worked great.
This day and age there are not many items one can say are an outstanding Value, This Diamond plate IS the Value for sharpening and keeping your hone stones Flat, I was wondering why it was taking so long to sharpen a straight razor? well my stones were a little dished out through the center so I was only sharpening on the edges of the stone , The Diamond plate changed all that, The Plate Can make a Huge difference in your sharpening too. I am going to buy several more.

I got this to lap a dished waterstone. It did a good job, but it looks like the stone may have worn away some of the 400 grit plate. We will have to see how it behaves in a year, for final judgement.On knives, both sides of the plate cut quickly, but the feedback seemed inconsistent. That could be me, though. I confess that I'm not a big fan of diamond plates for sharpening. Nevertheless, on a damaged, or very dull blade this would be a great starting point.
I have used the 1000 side to lap waterstones for straight razors and both sides to sharpen kitchen knives. Fast cutter - works very well on hardened kitchen knives. Great price! Had it for about a year and still going strong.
