Begin roughing out the stone. Using a heavy chisel, hold the chisel at a 45 degree angle and remove the majority of the stone and develop the basic rounded shape of the sculpture you intend to create. Never take out big chunks of the stone at once, rather make small cuts to ensure that the integrity of the stone is not compromised.
Create lines in the stone approximately 1.5 inches apart with your chisel as you make your way around. Once you make your way around the stone more than once, you will have multiple lines above one another. This allows small pieces of stone to be easily removed when needed.
Once you have removed the small pieces necessary for your sculpture, remove the lines created by the heavy chisel using your claw chisel. This allows the stone to take a more natural shape and helps you to come closer to your final creation.
Use the toothed chisel to remove the lines created by the claw chisel. Each step in removing the lines from the previous chisel is rounding the stone more and more, and allowing the stone to move toward it's final shape. Continue moving toward the final shape of your project.
Use the flat chisel to remove the lines created by the toothed chisel. Next, use the stone rasps to smooth out the final chisel marks and create the fine details of the sculpture. Move the stone rasp forward into the stone as you go (the rasp is intended to only go one direction and can cause serious damage to the stone if used backwards).
Use the file to remove the marks created by the rasps and to finalize the minor details of your work.
