The piso raut was a standard feature on most Iban and Kenyan mandau swords –a general utility knife, used for anything from splitting rattan to wood carving and, it was said, removing the flesh from freshly taken heads.
It is a long handled knife with short, single edge blade which was housed in a bark scabbard that was attached to the main scabbard with rattan. The terminals of the handles these knives were often decorated. This example, which is Iban, has a terminal featuring a stylised aso dragon head above a crouching figure.
Dimensions: handle 36 cm /14 ¼ inches; blade 11 cm /4 ½ inches.(If you are seeking a replacement knife for your mandau sheath, please send me accurate measurments and I will see if this one will fit)
