Pocket: The Peg and Worm Corkscrew

This Eighteenth Century idea is still clever and fresh - fit the crosspiece through a round loop in the top of the worm, and you're ready for business. Afterwards, the "worm" becomes a "sheath" - slip the crosspiece through the worm and into your pocket, and off you go!. Manufactured in the Eighteenth, Nineteenth, and Twentieth Centuries.

Comparatively rare - it's just too easy it to lose Peg or Worm!
