Miguel:

That is definitely elephant ivory on the hilt. The criss-cross pattern in cross section is typical of ivory.

As far as a snake or lizard, I can see the general form of a reptile but it may be something else. It's always hard to tell with these geometric shapes and without knowledge of the culture and its artistic preferences I would say it is difficult to be certain what we are looking at.
