Pop Top Soup Cans - The Death of the Can Opener
The pop tab addition to soup cans (and other cans) is, in my mind, quite a handy addition. Although soda cans have had these for years, it apparently took designers a few years to catch on and add it food cans as well. Last night a friend of mine tried to open a can of chili with my swiss army knife, and was lucky to not lose a finger. The jagged leftovers were quite sharp, and the process took quite a while. A can opener solves this problem, but you need to have one - requiring two tools to perform one task, something the tab eliminates. Sometimes I think the simplest design upgrades are the hardest to find when looking at traditional activities that have been ingrained into instinct over long periods of time. If it ain't broke, that doesn't necessarily mean that there isn't room for improvement.
Advantages:
Don't need the sometimes hard to find can opener
Edges are a little less sharp then can opener-opened cans (say that 5 times fast)
Disadvantages:
Requires a little more material?
