ferrule: [17] Despite appearances, ferrule ‘metal cap on the end of a stick’ has no etymological connection with Latin ferrum ‘iron’, although its present form has been heavily influenced by it. It is an alteration of an earlier virolle, which was borrowed in the 15th century from Old French. The Old French word in turn came from Latin viriola ‘little bracelet’, a diminutive form of viriae ‘bracelet’.
ferrule (n.)
"metal cap on a rod," 1610s, ferule, earlier verrel (early 15c.), from Old French virelle "ferrule, collar" (12c. Modern French virole), from Medieval Latin viriola "bracelet," diminutive of Latin viriae "bracelets," from a Gaulish word akin to Old Irish fiar "bent, crooked," from PIE *wi-ria-, from root *wei- (1) "to turn, twist" (see wire (n.)). Spelling influenced by Latin ferrum "iron."
