Identifying an Indonesian Dagger

[CharlesS]

Here is an interesting Indonesian dagger. The blade is likely early 20th Cent., while the dress is later. The quality curved pamor blade, featuring a wide fuller, is the primary point of interest.

At first glance one is tempted to call it a "badik"/"badek", but I am not so sure it really meets the requirements to be a badik. In many ways it handles and feels more like a jambiya, with a curved, heavy blade, and a much more shallow curve to the hilt than is typical of a badik. It is held as comfortably with the bottom edge out, like a jambiya, as it is with bottom edge down. This feature certainly is not characteristic of a badik.

Any comments, suggestions, or references to a more correct name for this piece would be much appreciated.
