Beautiful piece of work, Please wear dust protection turning Paua or Abalone, in fact any shell fish shell, I have several lapidary friends that have developed a disease almost identical to Mesotheleoma <sp> once the fibers are inhaled, they continue to grow, we used to cut tons of Abalone for making Fetish necklaces back in the early 70s we cut a lot of shell hishi before they started bringing it in from the Philippines. One of my Zuni friends died died a few years ago very slow and agonizing. the dust is deadly, but my heavens it's beautiful, And Abalone tastes SOOOOO GOOOOOD. I'd pay a kings ransom for a couple of fresh steaks.
