I have never liked or had any success using a twin prong cork pull …… until I used the Durand. My 65th birthday was November 23rd. My children came to town to celebrate with us. I was opening a ’61 Cantemerle, but the cork began to crumble. I then took out the Durand and removed the cork without further problem. We finished, appropriately with a ’45 Croft port. The 65 year old cork gave us no problem with our Durand. A brilliant piece of design and engineering. Many thanks.
