The advantages of carrying a credit card tool around with you are virtually endless. You never know when you will need a sharp blade, a bottle opener, or a mini serrated edge to complete some random task that you encounter. 

The beauty and advantage of a credit card tool over a traditional multi-tool or knife is the form factor. The fact that it is such a small and manageable size so that can fit into a wallet makes it infinitely more portable and less of a burden to carry around with you. Most of us already carry around a wallet wherever we go, so adding the weight of one, maybe two, credit cards to our wallet is a small price to pay to always have a multi-tool on us.

Materials and Form
Our Credit card multi-tools are made of stainless steel. They are the size of a credit card with a variety of bottle openers, saw edges, measurement edges, and other useful tools cut into them. 
Functions and Uses
The combination and number of different tools in a credit card multi-tool is dependent on the model and brand of the gadget. Everything from knife blades, saw blades, bottle openers, screwdrivers, measuring edges, and countless other tools can be included in a credit card multi-tool. What functions and tasks a credit card multi-tool can perform depends on what it has built into it. There is no shortage of options out there on the market today so it is pretty easy to find one that will fit your particular needs. 
Thickness
Our credit card multi-tools are around 2.0 millimeters thick. While standard credit cards normally come in at around 0.80 millimeters thick, the difference when you hold the two side by side is slight. Even with the added thickness, both the credit card knives and multi-tools should fit very nicely in a standard wallet. WeightUnlike the credit card knives we discussed earlier, credit card multi-tools often weigh a little bit more than a standard credit card. While a credit card comes in at between 0.2 ounces and 0.7 ounces, credit card multi-tools often weigh around 0.9 ounces. The reason for this added weight is that they are often made of solid metal for durability purposes.
