The Scratchers are tools for scratching 2.5 mm and 5 mm pitch on marble, stone and granite.
The staplers have removable inserts to allow them to vary their position and quantity. In this way the type and width of the finish is adjusted. The inserts are also designed to have a long life, as by turning the inserts up all the vertices can be used, thus multiplying the life of the tool.
The Staplers can be applied to all bridge or flag cutters with a horizontal shaft.
