It is a diamond grindstone.
This is used to keep the grindstone flat.
You can buy this item for about 27euros.

And the accuracy is also very good.
Keeping the grindstone flat is an absolute requirement for perfect sharpening of the blade.
It is also an absolute requirement to use this diamond grindstone to meet that condition.
Please try!
Let’s enjoy wonderful woodworking together!
It will start in Marseille from May!
