mandau with atypical blade?

[asomotif]

Good evening,

The blade looks concave / convex on the first 2 pictures, which makes it a mandau blade. Th egenaral shape is not atypical
The decoration that is visible on the last pictures looks indeed a bit atypical.

Better picture in due time will be nice.

Nice carved handle. the bronze sleeve is atypical, and probably even a later addition. Maybe a sleeve from a spear/lance that was modified ?
handles with silver sleeves are sometimes seen.

tastefull weapon nevertheless.

Best regards,
Willem
