刀匠

1. Origins, structure, and basic meaning

• Structure: 刀匠 (とうしょう) is a noun for a craftsperson who makes Japanese swords. 刀匠が marks the maker as agent, and 刀匠の名 identifies whose name is on a sword.
• Basic usage: The smith is the actor in the hammering scene; the name engraved on the displayed blade links the object to its maker.

2. Common pitfalls and similar expressions

• Sword maker at work and maker's name on a blade
  • 刀匠 has the specialized scope of sword making rather than merely any metalworker. 刀匠が marks the working agent, while 刀匠の名 builds the maker-name relation.
