Where does the saying 'not a bad old stick' come from?

The saying "not a bad old stick" is often used in British English to describe someone or something that is surprisingly good or reliable, despite initial appearances or age. It is thought to have originated from a more literal interpretation of an old walking stick, which, while worn, can still be functional and dependable. The phrase reflects a sense of understated appreciation, often used in a humorous or ironic context. Its exact origins are unclear, but it embodies a common sentiment of valuing practicality over novelty.
