Converted Golok?

[CharlesS]

Looks to be a Javanese golok though I can not explain the apparent damage and covered ferrule on the hilt, or the odd notch cut into the blade near the tip. Both seem to be old work, the hilt perhaps for a better grip, and the blade perhaps to make the blade specialized for a specific job as a tool. That's my best guess. I think it is a mid 20th century piece.
