Philippine Buyo Knife, Piso Raut, or Something Else?
 

The blade looks like a Philippine Buyo Knife, however, the handle, which I believe is bone looks to have carvings in the Dyak manner. The handle and the blade aren't in the Piso Raut configuration, but then again there is the carving.
The blade measures 6" and the handle 10".

Great knife! Carving ornaments are similar to those of Borneo

Hello David,

There are similarities but also unusual elements which might point to either Islamic influences or possibly even other islands. I can't really place this carving style with any specific group. Hopefully the Borneo specialists will chime in.

Thanks, guys,I think were on the right path.

This looks similar to a nautilus.

Interesting configuration. It looks to me like it was designed to get the hand using it out of the way. Skinner? Or meant to slice something on a table or the ground?

Is that a makara on the pommel?

The band below the know work reminds me of a motif we have discussed on the keris Janggelan style hilt as a mask or vegetal/insect/arachnid feature.

Below the makara(?) head is a detail that reminds me of the tree of life. On the same band there is a double spiral almost modified into a swastika. Here is a page from Van der Hoop that discusses the double spiral's spread through the archipelago.

The final bit on the pommel I can't help but notice has eight petals and a bud on top. Is this a feature derived from a lotus? I am probably reaching a bit with these interpretations, but it is what I see on this interesting knife. For some reason the decoration on the whole has the feel of water.

I think it's a Buyo knife from the size of it.
Form follows function, decoration would be regional for a tool such as this one.
Dyak design elements, but with other (?) elements also.
