This unique tribal weapon is a headhunter's mandau knife set made and used by the Dayak people living in Borneo (Kalimantan in Indonesian), Indonesia.  This mandau knife was used in the headhunting ceremony, where after tribes attached other tribes, they gathered the heads of their enemies to be used in various festivities.  The Mandau knife is both a work of art in itself and a weapon. It consists of a long knife with a dear horn for the handle which is carved ornately and strands of hair (human?).  The scabbard is made of two pieces of wood bound together with rattan and other natural vegetation.  The smaller knife fitted to a long wooden stick which is also decorated, was used to take out the brain out of the skull and other soft tissue of the head as well as sharpening, carving and other general use. Dimensions Total length in scabbard: 61 cm/24 inches Sword: 53 cm/20.8 inches Knife: 41 cm/16.14 inches
