I do love a glass of wine on occasion, and these occasions seem to be occuring with increasing frequency. I have a 'French waiter's' corkscrew with a leverage arrangement; and a double lever corkscrew; you screw it down into the cork and then push down on the levers and the cork comes right out. But I see corkscrews without the lever mechanism; they're particularly popular on knives. One of the most popular tools on the Swiss army knife is a corkscrew, although I prefer a Phillips head screwdriver as I get more use out of that. And original design Laguioles have a corkscrew as well as a prong for curing bloat in sheep (don't ask). But considering the force needed to budge the cork with a lever, I wonder if I'd have strength enough to pull one without this mechanism. How do you do it? Do you just screw the thing into the cork and give an almighty yank or is there something I don't undestand about this? Enquiring minds want to know.
