Can someone tell me what the name of the bit is that is used to do eyeballs. Have seen it at an exhibition, but do not know the name in order to buy one. It's concave and carves out a nice eyeball.

They are called Eye Tools. I dont think Milt sells them, but you can buy them from Jamie ..Here is a link
