Paving stone sawing or cleaving

Cleaving cobblestones involves breaking them in two with a specialised machine, after which the relatively flat fractured surface becomes their new surface. Cobblestones can also be sawn to achieve a 100% smooth surface. In this case, cobblestones are split into two equal parts, or the top of the cobblestone is sawn. Depending on the type of stone, sometimes one or the other treatment is appropriate. Getting twice as much surface area out of this kind of salvage operation is a great advantage.
