I work in wine and having used many corkscrews I have difficulty finding one that I really like. So far this has been my favourite for efficiency from a wine perspective. I personally prefer the nice sharp serrated blade over the blade on many others. It does take a slight change in technique to get a clean looking cut but it is still possible. I will admit however that coming from a winery perspective I may view the foil cut slightly differently. A previous reviewer noted that for table service he felt the foil was too chewed up, this may be the case for his perspective but I will note that a) I would prefer to have an efficient if not perfect cut due to pure volume of bottles opened and b) even in the case of table service I would prefer to get the foil in one go with a serrated blade rather than fumble around in front of a customer with a flat blade that one time when it decides it just won't cut.
As noted in the title, for the odd time when I'm serving beer the bottle opener is very awkwardly placed until you get used to it. Overall I like the corkscrew, it's efficient, cheap enough I can lose it and not really worry and still looks nice enough.
