This is arguably the best corkscrew on the market.
The finest corkscrew ever designed is a gadget called the Screwpull.
Actually there are three excellent models of Screwpull and there are some Screwpull imitators that work pretty well.
At the center of the concept is an extra-long, wire helix with an extra wide spiral. The tip is extra sharp so it will not punch cork bits into the wine. The screw is housed in a bracket that automatically aims the screw at the center of the cork, the point at which many of us go awry. However, the Screwpull's secret is that the helix is coated with a non-stick material that helps it glide through the cork effortlessly, and when it is turned all the way into the cork, even the most stubborn plug of wood floats out of the bottle as if weightless. It is idiot-proof and inexpensive.
