Izici:
Ibukhali, Iqinile
Inalithi yobulukhuni obukhulu, Yakhiwe ngensimbi ye-alloy tungsten
Idizayinelwe ukukhiya ngokushesha futhi ibhoboze ishubhu yesiqandisi
Gcoba ishubhu lesiqandisi bese ubuyisela isiqandisi esidala ngokushesha.
Kwenziwe ngensimbi ye-alloy efakwe ukushisa esezingeni eliphezulu ukuze iqine.
