This is provisionally identified as a “Luki”, a type of machete from Java, Indonesia. It was most likely used as an agricultural tool. The metal is a poor quality steel. In addition to showing the wear of use and time, the blade of this dao has numerous forging flaws and is generally unrefined. The blade has a crack, probably caused by hitting something harder than the iron, e.g., a rock in the soil.
