I prefer waiter-style corkscrews like this one because once you get the hang of using them they're simple, effective tools, much like a chef's knife. However, this particular corkscrew is very cheaply made: by the time I'd opened a couple of dozen bottles the hinge of the metal lever thingie (I'm sure the French have a word for it, but I confess my ignorance) became loose, so the lever flops open. It will still open a bottle, but it won't stay closed.
