## Description

Diamond Sharpener Atoma

Review: Great for flattening my whetstone! - 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.
Review: Fantastic - Love these plates ,,, perfect for honing
