A stoneworking or cutting device for texturing the surface of stones, in particular, concrete slabs has a tool holder in a, swing frame with a number of stoneworking or cutting tools whereby each tool is activated individually. To produce the striking force, a number of flyweights are mounted on the swing frame so that they can rotate, whereby the swing frame itself is mounted so that its height can be adjusted in a horizontally movable base carriage. Striking pins corresponding to the individual tools in the tool holder are made to oscillate by the flyweights to activate the tools which work the stone.
