Here are just a few tools that I use to carve the stone and create my sculptures. Most of my tools were purchased as I needed them to make the sculpting process easier and to improve the finished product. I would recommend taking a sculpting class before you invest a lot of money in tools. Some rocks are harder than others so diamond embedded tools are a must .
The finer details are executed using hand tools.
After removing the majority of the rock that's not required with the power tools then I use rasps, chisels, files and sandpaper to complete the work.
