We’ve all seen ads for credit card size multi tools like these:

Have you used one and found it lacking, or thought you’d like one if it were only useful?
Have ideas for the ultimate credit card multi tool?
Let’s hear, and better yet see, your ideas. Maybe we can come up with a design that actually is the ultimate. Hell, if our design is good enough, maybe we can even do a group make/buy.
RULES:
1. The design has to be the exactly the same size as a credit card and at most the thickness of 3 credit cards.
2. The design has to be one or more solid pieces. No hinges, electronics, or gimmicks. The only “complication” allowed is that if the design is two or more pieces, it can have a slip case or something to hold it together in a credit card shape.
3. The design has to be capable of fabrication at a low cost. No space-grown sheets of nano diamond laminated under solar core pressures or any of that BS.
Your call on what functions to have in the multi tool. It can be for camping, fix-it-ing, close quarters battle, whatever. But frivolous <> ultimate. Is it something you’d actually pay money for and carry every day?
