The Harden Professional Flat Cold Chisel Series (610805–610807) is engineered for demanding demolition, masonry cutting, metal chipping, and stone dressing tasks. Available at Marvisons, this heavy-duty hand chisel is forged from high-grade heat-treated carbon steel to resist mushrooming, chipping, and wear under repetitive hammer impacts. Featuring a wide flat cutting edge and a protective powder-coated finish, it provides excellent accuracy and durability when breaking through concrete, brickwork, mortar, and mild steel fasteners.
