Two months ago I highlighted the classic multi-tasking Swiss Army Knife. If that isn’t to your liking and seems a bit too bulky, you may want check out the Credit Card Survival Tool. As the name and picture suggest, this thing is the size of a credit card and includes eleven tools. It does have nine less tools than the Swiss Army Knife, but try fitting that knife into your wallet.
The Credit Card Survival Tool is a tiny multi-tasker that can really come in handy. Below is the a diagram highlighting each tools function.
