There is no mistaking a Bali-Song knife when you see one. The sheer design, action, and smooth rotation sets this knife apart from the rest. The Bali-Song knife, also known as a butterfly knife, consists of two handles that rotate around the blade, completely exposing or hiding the blade edge in one swift flip. Benchmade's butterfly knives are fashioned with titanium handles and can stand up to any challenge. View and customize our 85 Billet Ti Bali-Song and Morpho Family knives.
