Flexible combination of tools may be applied in actual use. Other tools include pencil, eraser, knife, whetstone, nicking tool, etc.

4. Re-cleaning: In the cutting and carving process, stains are often produced on the eggshell surface, so re-cleaning is needed to cleanse the inner membrane of eggshell with steel brush.

5. Decoration: The processing method from inside to outside is adopted. The internal decoration should be performed first to avoid cracking during the complicated decoration process. The external decoration is subject to the pattern design to fix all kinds of gold thread, diamond, claw chain, beads, metal accessories, music bells, etc. according to the planned procedures. 6. As the shell itself is fragile which increases the production difficulties and reduces the success rate, each finished egg carving product is an exquisite artwork.
