The stones blocks of mining that weigh from 5 to 40 kilos each, are led to special cutters with diamond disks and they are cut in desirable dimensions. Afterwards they are smoothed in specialized smoothing machines .
Mostly we don't use a cutting machine so we can preserve the natural thickness of the whetstone that would give a certain gravity to the final product.
So the thickness of the final product depends from the thickness of the initial vein of excavation that is approximately from 3cm to 12cm and sometimes even 15cm .
The surface of smoothing is used to be from 10cm to 25cm in length and from 6cm to 12cm in width.
