Here are a couple of photo's of the kris that I mentioned.
Both of them had pins holding the kakatua's crest in place. The pin on the ivory might have been inserted as a repair because the crest has a break in multiple places. The smaller bone kakatua, you can clearly see that the pin was used to hold the stacked pieces of the kakatua's crest at the onset of the carving.
