Armed Corkscrews - Making Your Life Easier
British product consultancy User Vision asked 500 consumers to rate in terms of usefulness a range of everyday products and services developed over the past two decades which have made difficult, inefficient, inconvenient or time-consuming tasks easier. On top of the list of 50 items were armed corkscrews, voted by 57% of respondents as in the top five most useful innovations.

Personally I prefer the Screwpull when I want to remove a cork as the armed corkscrews tend to breakdown when I use them.

I wonder if in 20 years we will see screwcaps on wine bottles in the list?
