What is your favorite corkscrew and why??
I'm a tad obsessed with finding the right corkscrew and I believe I've narrowed it down to the 'tradional' waiter's style... No 'Rabbit's or screw pulls for me (I have an 'Ah So', but have struggled with it to be honest).
The waiter's style suits me, and believe that the 'Holy Grail' of corkscrews for me is something that is large, heavy, open helix, traditional blade foil cutter, and (here's the hard part) a hinged 2 piece 'lever' that can adjust when you're at the second stage of removing the cork.
Many of the top models (Laguiole, etc.) have the 1 piece solid lever that generally have a second level built in, but does not have the flexible 2 piece lever. Even the one that is being heavily promoted in Canada, the 'Code 38 Stealth' model ($450!) seems like more of the same.
I just bought a beautifully made Legnoart model from Italy that had all of my desired features, but does not have the 2 staged lever - The same goes for the previous top model in my collection, the Vigneto 'Waiter's Friend' model - Very nice, but without the 2 piece lever I so desire (It also has a wierd internal circular bladed foil cutter that works maybe 50% of the time, and can only remove the upper part of the capsule vs. the whole piece, generally my preferred modus operandi).
There are few very cheap plastic type waiter's corkscrews that have the 2 piece lever, but they break easy, have no weight in the hand, are flimsy, etc. - Nothing of quality that I've seen has the desired lever.
The quest continues...
