Our Mosaic Hardies are imported from Italy for use with the Mosaic Hammer. We offer two different types of hardies. The Steel Hardie is the most durable and is suitable for cutting stone and glass. (For cutting glass, use with a carbide-tipped hammer) The sharper, but more fragile Carbide Hardie is for cutting thicker glass, like Dalle de Verre, and for high-precision glass cutting. Use the drop down menu to select your hardie.
