This keris isnt my family's heirloom, but my cousin's collection.
The pamor is putri kinurung, from Majapahit era, made in Tuban region. The Majapahit details can be seen from the iron which was dark-blue.
The pamor also form an andhap luhur, which meant that the pamor on each side is reversed. On one side, the pamor started from the bottom-up, while on the other, it started from top to bottom.
it has a very good balance too, as it may stand both on the bilah and the ukiran. Suprisingly, as a tuban keris, it was quite heavy too.
For more detailed pictures of this keris and some of our (me and my cousins) other collection, please visit beraswutah.blogspot.com - a small online gallery we put up to attract young Indonesian youth to love and preserve our national (and UNESCO acknowledge) heritage
