I have this knife handle for quite some time. It's a good thread to show it.
The seller told me it was from the Geelvinckbay, PNG. According to the information I got, it was collected in 1961 in Biak (Dutch PNG) and brought back to Holland by someone in the military.
It's made of some kind of lightweight wood. There's no blade. At the base, there's a small groove in which to fit a blade. I don't know which blade would fit into it as the groove is very shallow.
Total length : 15 cm
