Cardsharp 2: The credit card folding safety knife

That's some credit card you've got there, is likely to be the first thing people say when you whip the Cardsharp 2 credit card folding safety knife out of your wallet.

Created by Iain Sinclair and made from polypropylene with a 65mm stainless steel surgical blade, it transforms from a credit card shape into a knife with a couple of folds.

Costing £15, it weights only 14 grams, making it ideal to slip in your bag on your next adventure and the blade is certainly sharp enough to cut through most things. We diced a tennis ball with no problem, while food like tomatoes and bread proved equally easy.

To give you some protection when it's in your bag, the blade comes with a simple locking mechanism. When folded, it is just three folds and there's plenty of grip to get a good purchase.

The catch for having something so small and light is that you won’t get any other tools or uses for this as you would a multi-tool - but then how many of those can you fit in your wallet?
