I think the blade is older then the handle and the sheath. All wooden sheath, decorated on one side. The two pieces of wood are held together with 3 rattan bindings. Wooden handle with copper ferrule. The blade is very sharp and is a bit 'hollow' on one side (like you see on a mandau).
Total length : 51 cm
Handle : 9,5 cm
Thickness of blade near the handle : 6 mm
