Wiktionary examples

These source excerpts show how ferrule appears in context. They illustrate usage; the definition above remains the entry’s reference meaning.

  1. The cane was produced in court; it was as stout as an old-fashioned club, and of terrific weight. The man who wielded it must have been very powerful, for he had only dealt one blow, but that blow had cracked the old man's skull. The cane was undoubtedly of foreign make, for it had a solid silver ferrule at one end, which was not English hall-marked.
  2. He walked on, waiting to be spoken to, trailing his ashplant by his side. Its ferrule followed lightly on the path, squealing at his heels.
