 This make much more sense to me. The larger back teeth of the sperm whale especially would provide both the length and mass necessary to carve a reasonably sized hilt. Here is a large scrimshaw tooth as well as a nice keris hilt purported to have been made from a sperm whale tooth. I suspect that this is the material most often used where claims of dugong have been made.
