Two Nice Parang Naburs

[CharlesS]

I really like parang naburs...they have such a unique appearance, and generally handle beautifully, with chunky hilts and heavy, well balanced blades. They can come in tremendous variety, but these two are two exceptional examples, one with a dressy scabbard, the other with a more simple scabbard. Great hilts and teriffic blades on both. Does anyone know the purpose of the extended screw often found on the end of the hilts of these??? Note that one of these has it, and the other has a permanent cap where the screw could be.
