When to Use Your Credit Card Knife

How many times have you searched the house or office for a knife or scissors to open a package that just arrived?

If you’ve ever had your glasses come apart at work, a colleague point out a string hanging from your shirt, or found yourself struggling to remove the twine from a bale of hay so you can feed your horses, you understand the frustration.

You may often find yourself thinking that you could do something quicker and easier if you had the right tool. But you can’t just carry a knife or scissors everywhere with you.

A credit card knife comes in handy for:

  • Opening package
  • Cleaning and Preparing Fish
  • As an Eating Utensil
  • Sharpening Sticks for cooking or hunting
  • Cutting twine, zip ties, or rope

How to Choose the Best Credit Card Knife

There are so many credit card knives for sale on the market today. How do you know which credit card knife to choose? Below are several factors to consider and compare when you are comparing options among the best credit card knives.

If you think about each of these carefully in relation to your own preferences and needs, we’re sure you’ll be able to select the credit card knife that is best for you.

Knife Function

The function of a knife can be a crucial difference when you are considering the various options for credit card knives. Some credit card knives are not really knives, but are more of a straight blade, sometimes resembling a nail file or a letter opener more than a knife.

It’s important to understand how you need your credit card knife to function in various situations and to identify how the blade will funcion when you need to rely on it.

Credit card knives often come as just one piece of a multi tool. Determine what other tools you need to have as part of your EDC and weigh that carefully when choosing the best credit card knife for you.


Look for a credit card knife design that is easy to open or to unfold or fold to close. Some credit card knives are just that, a knife. Other credit card knives have additional tools built-in to the design which may or may not interfere with things like the grip, function, and reliability of the knife itself.

Several credit cards have a detachable knife blade which can be removed if you are traveling or visiting somewhere that prohibits any kind of weapon.

Blade Material

The material used to make a good credit card knife is a critical component. Look for a steel blade credit card knife whenever possible. Stainless steel is nice to have because of its durability and rust resistance.

Experienced preppers looking for a reliable survival knife that can step up as a self defense weapon in a pinch will want to look for the VG-10 steel blade like the one in the SOG Access.


The knife should be designed with a secure locking mechanism that prevents accidental opening if carried in the wallet or pocket and that locks the blade in place when opened so it doesn’t accidentally close and cut you.

The grip of the knife should be comfortable and secure to prevent slipping, especially if you intend to ever use it for self-defense.

These credit card knives vary in their function but we’re sure that you can find at least one that will meet your EDC needs.

  • Are Credit Card Knives Legal to Carry?

Whether or not credit card knives are legal to carry will largely depend on where you live or where you are traveling to. In most cases, the length of the blade in a credit card knife will determine whether or not it is legal to carry.

In some countries or regions, it may be illegal to even purchase credit card knives as in the case for most Australian states. In many places, knife blades under 3 inches long are legal to carry. Check your local and state laws carefully to be sure you understand any restrictions.

The TSA has issues a warning to travelers about credit card knives when it comes to traveling however. Trying to take a credit card knife, or any knife of any size onto an airplane will result in confiscation and potentially additional consequences.

TSA agents realize that some travelers may simply forget that they are carrying a credit card knife until they go through the security checkpoint. For this reason, some checkpoints will offer you the chance to return the knife to your car or give it to someone outside the security line.

One Denver airport checkpoint offers a mailer you can use to mail your credit card knife back to your address from the airport before boarding the plane. If you are planning to travel consider a credit card knife with a removable blade so you can leave it at home when traveling and still have the remainder of your tools with you.
