noun

blunt sword with a tempered edge

Original literal meaning: a sword made by welding a hardened steel edge onto a softer iron body, producing a blade that looks sharp but is actually weak. Now mostly used to explain the origin of the figurative sense.

• 「付つけ焼やき刃ば」とは、もともと焼やきの入はいった刃はを付つけた粗そ悪あくな刀かたなのことだ。

  Originally, 付け焼刃 referred to a poor-quality sword made by attaching a tempered edge.
