I've been a blacksmith for years now, and I can safely say that Corkscrews pose certain challenges along the making process. They can't be too bulky, or they will tear up the cork, and if they are too delicate, they can snap off in the bottle.
These corkscrews make a great, durable, elegant gift for the serious wine connoisseur or it's an exalant conversation starter at your next dinner party.
