Before we even bother telling you about this thing, let’s make one thing clear – you won’t be able to take it through as hand luggage at the airport. No matter how much you argue. No matter how much you attempt to bribe the security guard. Well, we imagine everyone has their price, but it’s very unlikely you’ll ever be able to take this through security at the airport, so don’t bother trying!

If you are bringing check-in luggage though, a pocket knife can prove all sorts of helpful – and it’s especially a travel essential if you’re going to be hiking, climbing or up to any adventure antics while you’re on your holiday. Pick one that’s got not only a good, strong blade, but a screwdriver, a pair of scissors, even a pair of tweezers, and – essentially – a bottle opener. You can’t go wrong with the Victorinox Explorer Pocket Knife.
