What about these card knives?

I have a Swiss card knife gadget that comes with a toothpick, tweezer and a small pair of scissors.

I have also seen another instrument of similar design.
I am wondering how useful are these flat, rectangular stuff.

Personally, I have mixed feelings about this card knife. Somehow, I don't think it is catching on, even though it had its novelty effect for a while.

Have anyone come across a real great one which beats all the others of similar design?
 
I too have a Swiss Card, which I received as a gift, however, it never has caught on for me to be of any use, so I consider it a novelty item. When I need a knife I reach for my pocket, not my wallet. Personally, I always carry more than one knife, so even if I needed a backup, I still would not have any use for a credit card knife.
 
I like the idea, but the Spydercard was a little too thick for me. Didn't go in my wallet the way I wanted it to. I'm sure it's solid and a good cutter, though.

I like the look of the Microtech even more--especially the curvy edge--but I don't think it's any thinner.
 
I have a Spydercard and like it a lot. I don't carry it in my wallet, because it makes my wallet too thick and heavy. Instead, I carry it alone in either my other back pocket, or my front pocket. You don't need to carry a "wallet knife" in your wallet! The great advantage of the Spydercard is how flat and comfortable it is, even in loose pockets as in dockers.

The thing to remember is, the primary design goal of these credit card knives is the form factor. Everything else, no matter how well-done, is secondary to that. So it's not going to have the ergonomics of your traditional folders. As long as you're expecting some tradeoffs, with carryability of the credit card knives going way up and the ergonomics going down, you won't be disappointed. Speaking for the Spydercard, I've used it as my primary knife at times and it is up to the task.

The Microtech Option II is a bunch thicker than the Spydercard. My had a bad lock so I sent it back, still waiting for a replacement. It remains to be seen if I'll find the thicker Option II carryable enough to replace the Spydercard.

I carry my MT Option II every day but I don't consider it my EDC... if that makes sense.

It's a great knife to have around in a pinch and Columbia makes the ideal wallet for it :)
 
The Microtech looks neat, might have to pickup one of those soon. I wonder how they would fair against airport security since they always have you remove your wallet, change, etc.. and place them in to a bucket with the guard on the other side?
 
Considering the fact that they are confiscating tweezers and nail clippers right now, I'm thinking putting one of these in a change bucket in your wallet is courting a date with a judge and lawyer.

A guy in Phoenix is sitting in jail right now because he taped some non-magnetic knives to his leg.

I enjoy my freedom too much to push that issue. I'll either drive myself or play by the rules when I fly.
 
If your primary interest is in a wallet-sized knife I would recommend the Spyderco SpyderCard. The Microtech Option II looks like a great design, but it is just too thick for my purposes.

If, on the other hand, you are interested in more of a pocket tool, along the lines of the SwissCard, I highly recommend the Tool Logic[/

has to be the smartest design for a CC sized knife ever.

and yes - MT looks close - too close...
 
I have three, and they are the Spydercard, SOG Access, and a Tekna CC knife. The one I like the best is the Spydercard, because it feels comfortable to me, and fits in my big wallet just perfect. However, I am seeing a little bit of rust forming on it.
