A badek or a pisau?

[A. G. Maisey]

This is badik blade that has been redressed in Solo, Central Jawa.

The blade is probably 19th century.

The locket & chape are silver, hand engraved, the wood in the fittings is Javanese sandalwood. These fittings are of premium quality.

The smell is not frankincense, it is sandalwood oil.

In Solo, this would be termed a cundrik.

EDIT:- the wood may not be Javanese sandalwood, but rather scented sandalwood, it would be unusual to include a knot in a scabbard made of Javanese sandalwood, but it would not be unusual in a scabbard made of scented sandalwood. In finished condition both woods look very similar, and this is premium quality craftsmanship, in which case it would be more likely that scented sandalwood was used.
