A Modern Jambiya with Old Hilt (?)

[ALEX]

Here is a contemporary Jambiya from Yemen. On a first glance nothing special new knife, but looking closely the hilt appears to be older, with traces of silver? filigree at the base. The scabbard fits perfectly so everything was made together. Also, it appears to be fibrous structure although it is not clearly rhino to me, there are no visible "tips", etc. Would love to hear any opinion on on the hilt, age and material. Thanks much!
