I came across this mandau with some faults, the tip of the blade is broken and the scabbard back piece is incomplete.
But the front piece of the scabbard is unbroken and shows in up a very nice and deep carving and the blade is very hefty.
I want to share it here specially for the very nice carving on the scabbard's front piece and maybe someone will be able to tell me from which Dayak group this piece is coming. All comments are very welcome.
The sword is 61 cm long, blade is still 47,5 cm long and 9,3 mm thick behind the handle.
