I want to talk about one of my favourite things, my corkscrew. There's just no better instrument to open a bottle of wine with, and everyone should own one.
Corkscrews/sommelier knife, whatever you want to call it, is the most effective cork extraction tool. And no one makes it better than Chateau Laguiole.
They make them out of different materials, but they're all hand made. Mine is stainless steel, with an African Bull horn handle. The weight feels perfect in your hand, and really makes opening corks pleasurable.
Didn't really know what I was doing when I started, but I think I got it down. Cut the foil, screw in off-center, tap the lever, and pull. Simple.
