Most of us are cutting materials like aluminium, wood, plastic or steel. This guy is cutting stone, Jade to be specific. As defined on Wikipedia, “Jade refers to an ornamental mineral, mostly known for its green varieties. It can refer to either of two different minerals: nephrite, a silicate of calcium and magnesium, or jadeite, a silicate of sodium and aluminium.”
Obviously it’s cutting characteristics are a different beast.
Thanks for sharing. It’s another great example of creativity and ingenuity. This is the kind of stuff that is exciting and inspirational.
The result looks great!
