Nice little Sumatran (?) dagger for sharing & comment

[Sajen]

Hello dear members,

I got this little dagger in a trade with a friend not long ago. I think that it is Sumatran in origin but could also be Malay, I am a little bit unsure.
Handle and scabbard are from wood and it's delicately carved, the blade is laminated and shows a batu lapak motif at the base.

26,5 cm inside scabbard, 23 cm without, blade 16 cm, 6 mm thick at the spine behind the bolster.
