Small rencong or???

[asomotif]

Hello Henk,

The gas lighter clearly shows the size and with this size handle I would not consider it a weapon.
The blade and handle are shaped like a rentjong, but I think it has been some kind of "trench art" by a soldier stationed in Indonesia.
Maybe someone with access to leather working tools for the scabbard.

More of a letter opener than a weapon. Pretty rare form though

best regards,
Willem
