The assembly line manages the final process, including inspection, quality control, and adjustment. The left and right pairs of scissors are made separately on the production line, and are then combined for the first time on this assembly line, moving on to the combining process. It is not just a matter of combining the scissors; it is the experienced eye and teamwork between line workers that determine which parts have the best left and right balance, and the way they are combined is changed depending on the type, resulting in higher quality products.
