Just added for reference.

Not as refined as that in post #25, but of similar blade style and pamor overall.

This is one of my favorite Pamor variations. The skills to do it well with hand tools is impressive. Yours, Ric

Ric, the traditional belief is that it took an mpu a lifetime to learn how to produce Ron Duru pamor, and that he made his first & only Ron Duru just before he died.

When Pauzan Pusposukadgo made his first Ron Duru a couple of his friends asked him if he was getting ready to leave this world.

Pauzan was a Surakarta Kraton empu, he passed in 2014, I forget when he made his first Ron Duru, but it was probably around 1990. At that time the process had been forgotten, Pauzan worked out how to produce Ron Duru by experimenting with plasticene.
