Synonym for handicraft on here will be Skilled work.
Step-by-step explanation:
Skilled work is not a direct synonym to the world handicraft as much as a worldly slang word for it.
Skilled work has come to describe any sort of work that requires the skill of hands and is often considered apart from the mechanical reproduction of products which is not possible with handicrafts.
The mechanical reproduction thus managed cannot be done for products made by hand like in handicraft and hence it is called skilled work as it requires human skill for the work to be done not mechanical skill.
