From Gizmodo:

The only withdrawals you can make off of this credit card are the steaming innards of your fiercest enemy (terrible interest rate!). They can hide a knife pretty much anywhere these days, can't they?

The CardSharp...measures just 2mm thick, weighs 13 grams...It won't be out until January for around $23...

I like that! Will probably get one when they are released.

Until then, I use this:

Stand back or I'll shank you with my Centurion card!

I used to own a credit card tool kit like this:

It broke after carrying it around for a few months. Not sure what materials this knife is made out of, but if there is any plastic involved I would avoid it.

The one I linked is solid metal and fits nicely in my wallet. I keep it in the leather sheath to avoid my wallet and fingers getting damaged.

You wouldn't use this thing as an all purpose tool every day, but it could just work in a pinch. If nothing else its nice to always be the guy that has a bottle opener
