Handy Credit card Knife
This is a handy little knife. Perfect for opening up packages. A few things that disappointed me was that its not stiff once in credit card state, and its a little flimsy to use. Will you be using this all the time for all your knife needs? No. But you will find it very handy for when you just need a quick cut. At the current price of $5 its a very good purchase. I myself got 4 of them to have in various places. Just remember to take it out of your wallet if your going to fly. I don't know how TSA will feel about this in your pocket. :)
Awesome useful knife
Great small foldable knife for opening boxes etc
Bought 6 of these because after my first one arrived a lot of my friends loved the design and asked me if they could have mine
Great concept but not so great execution
The card is very flimsy and mine doesn’t even stay closed. You MUST hold onto it firmly, otherwise it will quickly close and may end up cutting you. It IS very sharp however, which I like.
A bit flimsy
It’s cool if I can do it again I wouldn’t buy it.
Love the Card Sharp!
Easy to use and handy! Beautifully tucks away in the wallet.
