Atoma Diamond Sharpener Coarse Grade 140

Very happy with how quickly this flattens my 1000 grit whetstone. I was considering the atoma 400, but very glad I didn't because it would take me a lot longer to flatten my stone with the 400. So if you're unsure which to go for..you will be very happy with the 140 grade over the 400! If you're wanting to flatten a whetstone with a much higher grit, say above 5000 grit, then maybe opt for the 400 instead.

Love these plates ,,, perfect for honing

I use this to flatten my whetstones after use. It does that job brilliantly. Not showing any sign of losing it's efficiency after a dozen or so uses

Just in case you don’t know Atoma sharpening plates are the best that you can buy I have used them for many years now and they are just the best a bit more expensive but they last for ages so I can highly recommend Atoma sharpening plates.

I used this a part of my plane and chisel lapping process. I found it very gritty, it gives the impression that the diamonds are loose, it could be a bedding in process. It's also not 100% flat, I measured it yesterday and can get a 0.002” feeler gauge under a straight edge, not sure what the tolerances are. I would prefer a ferritic base, as for small items I use a block with magnets to hold the item flat against the surface.

This works well for sharpening and flattening. If you have chips in the iron I would use some sandpaper first at 80 or 120 grit but after that, this, a 400 and a 1200 before a strop will get your tools sharp.

If you are willing to pay for quality, this is the diamond whetstone to get. Make sure you get the correct coarseness grade.

Quick to re-profile your knifes with little effort. Worth every penny.
