world map polished handmade crude cubic stoneUp to thirty years ago, by coming close to a quarry, the tinkling of the hammers was heard on the steel tools and the rumbling of some compressed air pistol that prepared the "Cognare" to cut the stones. Today we hear the loud noise of diamond saws and air bocciarde. The quarries have been transformed into modern laboratories that produce perfect works and the stonecutter can work only thanks to the connoisseur or realizing works that machines can not do as "Opus incertum", pavements with pierced stones, works in frontage, restoration on rustics recreating to the originals. In the period in which the noise prunus mahaleb in trachite vaseof the steel of the "Ponciotti" and "Giandini" was still heard, in other words the "Irons" that were used to cut and trim the stone, were often obtained from the steel of the axles of the trucks then forged and beaten and finally tempered to meet the requirements of the stonemason. Stone spikes are still today octagonal steel rods of 17-18 mm in diameter, cut in pieces then forged, beaten and tempered, adapting the steel to the hardness of the stone. The chisels were of the same kind as the tips but prepared at the end forged with a cut. Today the few stonemasons still use their tips as tempered as they used to be, or they use the mason's hexagonal or the harder ones with the tips in Widia; the real stonemasons or stoneccuter improvise smiths by forging, beating and tempering according to the stone to be worked. The "Giandini", chisels and bocciarde have now usually plaques in widia. The hammers used are the equivalent of about 1 kg for the common jobs, smaller but with the same form to make high-low relief, about 5 kg club to beat the "Ponciotti" that cut the stones. The handles of hammers as per tradition, are usually made with wood of "Bagolaro" or tree of the stony (Celtis Australis), given its qualities of hardness and elasticity. The branches are cut and left to rest for a couple of years and then processed according to the handle desired.
