Character by character
Origin and story
Historical fictionIn chapter 70 of the Romance of the Three Kingdoms (三國演義), the veteran Huang Zhong faces Zhang He. Zhang mocks him for taking the battlefield at his age. Huang responds that, although his opponent treats him as old, the treasured blade in his hand has not grown old. The scene makes his weapon stand for undiminished martial ability.
This is dialogue from a historical novel, not a verified quotation spoken by the historical Huang Zhong. The idiom extends the image to experienced people whose ability remains sharp. It can praise an older performer, craftsperson, or athlete, and does not require a literal sword.
