Many of us know the annoyance of trying to use our keys to open a package, or having to use some effort to go and get a knife. Or the annoyance when you're having a get together and the only bottle opener in the house has miraculously gone missing. Well be annoyed no more! As with the 'Porter Key Knife' multi tool, you can do both of those things with the same item. Not only is this product useful, but being disguised as a key and going straight on to your key ring, it doesn't bother you any more that any other key would, meaning no carrying around the existing larger clunky multi tools in your pocket.
