The wood is polished with care and retains its natural colour. The mechanical elements are prepared and finished with extreme precision: internal polishing of the tone holes is done in line with Buffet Crampon’s high standards, developed with their expertise over the decades. The individual parts are set and protected by metal rings in order to limit any risk of splitting or cracking. The keys in maillechort (an alloy of copper, zinc and nickel) are cold-forged, and are copper and silver plated. The mechanical elements are carefully assembled and adjusted by expert technicians.
