The craftsman carves his own name, address or year the sword was made on into the Nakago (core) as Mei (an inscription) with a Tagane (borer). Generally, the name and address of the sword craftsman are inscribed on the front side (outside when wearing Tachi or Katana), and the year or name of the owner in the back side, but there are exceptions such as back-inscription or no inscription at all. This is the end of the work for the sword craftsman, then a Togi-shi (polisher) polishes the sword finally, but before the Muromachi period, the sword craftsman himself also polished the sword. There is a big differences in polishing Katana compared to other cutting tools; ensuring ornamental elements of a Katana, as a craftwork, is focused on as well as assuming sharpness as a cutting tool, and the whole body, not just the blade part, is polished.

After all the process of forging, Saya-shi (Sheath craftsman) creates the Saya (sheath) appropriate to the Katana. Katana are not completed soley by a sword craftsman, other craftsmen including a Togi-shi (polisher) and Saya-shi (Sheath craftsman) add the finishing touches.
