Here are some of the key tools that I have been using for this project and that sculptors find useful.
Boxwood tools are light and easy to use. the smooth surface make them brilliant for carving fluidly
Calipers are important for measuring distances. They are used extensively for head sculpting to obtain as much accuracy as possible.
Loops come in all different shapes and sizes you can get sets with multiple loops or one handle with interchangeable loops. They are good for scraping and removing material.
The dentist tools and the shapers are good for getting into all the smaller areas and parts that need more detail. The shapers can be used to soften lines. Some of the sharper and more pointed dentist tools can be you to cut material away.
