I bought a double hinged one off Amazon. Made in China, came with a wine stopper and a aerator as "gifts" for $6.95. On mine the foil cutter is a nail breaker; way, way, waaaaay too tight. I can't open it unless I put something on the sharp side to force it open. I don't really care because you can simply pull the foil off with your hand instead of cutting it - I am not a waiter, so there's no need for any type of show. The actual corkscrew function works great, it's almost effortless to pull corks. It looks like the Hi Coup linked above, but mine is logo free, which is IMO, a bonus. To me, it seems that all the fatter double hinged corkscrews you see are probably the same, or very close, with very slight design variations (private label logo, cross hatching or smooth lever, handle material). I bought someone else an unbranded one, but from a different vendor - looked to be exactly like the one I bought myself, but different scales, and this one had a foil cutter that wasn't a nail breaker. The fat ones all seem to have a spring loaded two step lever.
I also got a TrueTap Timber (I think that was the name). Was like $8.99. Foil cutter isn't a nail breaker, but the lever and handle are slightly misaligned. Also made in China. I picked that one instead of the other TrueTap models because I don't see the point of the non stick coating (or maybe just black paint) on the worm - I feel like it's probably just going to flake off anyway. FWIW, there are pictures of corkscrews that look like the TrueTaps with the worms all hilariously bent out of shape. Despite being made in China and appearing to be the same design, you would hope the actual TrueTaps are better made. TrueTap also offers the fat type like above. Fake edit - found it -

Unless you need to impress someone or just want something nice for yourself, I don't see any real reason to spend the money on a (made in France) Laguiole, and certainly not the Code 38.
