I actually prefer the simple can opener of my old swiss army knife or off a Leatherman. I also prefer a simple corkscrew bottle opener with knee joint to any of the highly complex new fangled jobs. When my girl told me her favorite bottle opener she ever used was one of those battery powered alibaba automatic bottle openers I genuinely jumped 2 meters backwards and made a screeching sound. I like things simple, things that are made to last.
