The term 業物 (わざもの) is composed of 業 (わざ, 'work' or 'skill') and 物 (もの, 'thing'), literally meaning 'a thing of skill'. It is traditionally used to describe a sword that is exceptionally sharp and well-crafted. The exact historical derivation is uncertain, but it is associated with the appreciation of fine blades in Japanese culture.
