5. Trimming thiab Finishing:
• Tom qab txias, cov khoom ntau dhau ntawm ib sab yog trimmed. Cov khau raug tshuaj xyuas rau tej yam tsis xws luag thiab polished los txhim kho nws cov tsos.
6. Kev Tswj Xyuas Zoo:
• Txhua lub khau tau txais kev tshuaj xyuas zoo rau kev ua raws li kev tsim qauv, lub zog, thiab cov qauv ua haujlwm ntev.
7. Ntim:
• Cov khau tiav tau ntim thiab npaj rau kev xa khoom.
