Why are the names of the workshops and artisans in charge of each process listed in the product specifications?

The hands involved are different. An A6-size refill notebook lists three workshops, and a leather pencil cap lists a processing company alongside the name of a single artisan. When listing product specifications, Kakimori does not lump them together under one manufacturer, but breaks down and records the steps gone through until the item is completed.

It follows the flow of processing in sequence. In paper refills, different specialized workshops respectively handled cutting the paper to standard size, print processing such as foil stamping and contour die-cutting, and binding multiple sheets together^[1]. The leather pencil cap was also created with a specialized company that cuts leather to shape and an assembly artisan who sews and completes it, each participating under their own names^[2].

In Tokyo's old workshop districts, a culture of division of labor has long continued, where items are completed by passing tasks to the most skilled artisan for each process.

hmmm, the names of the people in charge engraved on the specification sheet clearly reveal responsibility for the processes, while showing intact the traces of the countless hands that went into making a single object.
