Definition: double-bladed corkscrew

Also known as a bladed corkscrew.

In the cellar lies a very old bottle. Dusty and venerable, it has stood the test of time. Its vintage dates back several decades; promising, it is time to appreciate its contents.
The label barely reveals the name of the estate, due to the damp cellar, which is excellent for the contents of the bottle. The cork seems to have fulfilled its protective role. The level of the bottle is excellent; ultimately, everything is in place for a superb moment of gustatory delight.
From there, the only difficulty remains the unknown factor resulting from such long ageing, which concerns the condition of the cork in this venerable bottle. Even the best corks weaken with age. For this reason, some large estates offer a service to replace and recork bottles with a new cork.
There is a solution for opening such bottles without apprehension or risk, even with corks that are crumbling, weakened by years of contact with alcohol in particular.
This is an essential tool for opening old wines, or even more common wines, with stubborn, stuck or crumbling corks. The disadvantage of the traditional corkscrew is that it requires piercing the cork. On a cork of good consistency, this piercing in the centre of the cork has no adverse effects. On the other hand, it generally causes permanent weakening of corks that lack resistance.
Above all, do not insist, remove the corkscrew gently and use a blade corkscrew.
With this two-bladed corkscrew, you can open a bottle even in the worst situations.
It is very easy to use, even if it may seem strange at first.

How to use it:
This corkscrew consists of a handle with two fairly flexible blades that are slightly curved outwards at the ends.
After removing the foil from the bottle, simply insert the blades carefully. The left blade is longer than the other, so insert this one first, followed by the other.
The blades slide between the cork and the glass with ease.
Then, push the blades in with a flick of the wrist, moving from left to right, using an alternating pushing motion.
Once fully inserted, the handle will be in contact with the cork.
From this point on, you have a secure grip for extracting the cork. Gently pivot the cork, which is now trapped between the blades, while pulling it out smoothly.
The cork will slowly come out and you will then be able to retrieve it between the two blades.
After one or two attempts, you will have mastered this magnificent tool.
