A queen grafting tool is a specialized beekeeping tool used in queen bee rearing, which involves transferring bee larvae from worker cells into specially prepared queen cups to raise new queen bees.

Queen bee rearing is an important part of beekeeping, as it allows beekeepers to propagate new colonies and replace aging or underperforming queens. By using a queen grafting tool, beekeepers can ensure that the bee larvae are transferred to the queen cups with minimal disturbance, ensuring that the new queens are healthy and strong.
