The Sketch Book of Geoffrey Crayon (1819-1820), 'Rip Van Winkle'
A tart temper never mellows with age, and a sharp tongue is the only edge tool that grows keener with constant use.
Behind the line
What it means
Our interpretation.
This wry aside claims that a harsh disposition doesn't soften with the passing years, and unlike most things, a cutting tongue only becomes more effective through frequent use. The comparison to a well-used blade suggests habitual sharpness sustains itself, growing more precise the more it's exercised.
