Who invented the corkscrew?

It is unknown who made the first corkscrew. The first corkscrews were derived from a gun worme, a tool with a single or double spiral end fitting used to clean musket barrels or to extract an unspent charge from the barrel. By the early 17th century corkscrews for removing corks were made by blacksmiths as using a cork to stopper a bottle was well established.
