Pyrophyllite has low hardness and many cracks, so it is not suitable for large-scale stone carving equipment (especially for beginners and non-professionals, it is impossible to make large-scale works).

1, miniature power tools (complete sets, Taobao is generally around 100 yuan ~200 yuan) are used as plastic embryos;

2. Cutting tools. Generally self-made, can use file, saw blade restructuring;

3. Line carving tools. Mainly used for backing, seals can be written directly with single and double knives.

4. Coarse grindstones and fine grindstones;

5, water grinding sandpaper;

6. Soft brushes and hard brushes;

7. Polishing materials;

8. Tea oil (main). Mainly soaking stones.
