### ⭐⭐⭐⭐⭐ Great stone flattener
*by M***S on 16 January 2026*

### ⭐⭐⭐⭐⭐ Just the best
*by J***N on 3 January 2026*

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.

### ⭐⭐⭐⭐⭐ Amazing product
*by A***K on 11 September 2019*

Great for leveling your stones, saves your time massively if you're professional chef. I use it on my chosera's and shapton stone's. It can leave small scratches on them, but after few strokes with your knife they gone. I have Japanese single bevel knifes, so I really need my stones flat and that atoma is massive help.
