Buyers’ Guide: Considerations for Buying the Best Credit Card Knife

Before you choose a credit card knife which will be best suited to your needs, there are several considerations to bear in mind. Let’s take a look at a few of the most important factors.


The portability of a credit card knife is a crucial factor to take into consideration when it comes to buying the best model. Not only must they be lightweight, but they also need to be small in size and thin in their design. Credit card knives are designed to slide comfortably into your pocket or wallet as a regular card would, without creating any bulges. A sleek, lightweight knife makes it all the more comfortable and functional when you’re using it and carrying it around with you.


As you may have noticed while looking through our list of the top ten best credit card knives, you’ll often be able to get hold of a multi-tool which incorporates a credit card knife. It’s likely that you’ll be using your knife while camping, travelling, and during survival situations and so a credit card knife which integrates other capabilities such as a bottle opener, ruler, magnifying glass, and nail file will come in handy.

Blade Materials

The quality of a credit card knife is largely based upon the materials used in the construction of the blade. To ensure longevity and durability, we would recommend opting for a knife blade made from a high-quality stainless steel or aluminum. As with any knife, you want it to be effective, sharp, and able to withstand heavy usage.

Safety Lock Mechanism

A safety lock is another important feature to look for if you choose to purchase a credit card folding knife. Aside from being a legal requirement, safety locks will also protect you from accidental injury. In terms of functionality, the safety lock needs to be of good quality and not inhibit the folding mechanism.


As a credit card knife is intended for use as a survival tool, it needs to be constructed from rust-proof materials. A quality blade made from stainless steel or aluminum materials will prevent rust and ultimately increase the longevity of your knife.


Now that we’ve taken a look at the ten best credit card knives and the considerations you’ll want to take into account before making your purchase, we know you’ll have a few questions. We’ve compiled a few of the most frequently asked questions when it comes to buying the credit card knife which is going to be best suited to you and the activities you intend on using it for. Let’s go through our answers.

1. What is a credit card knife?

A credit card knife is a knife designed to be stored inside your wallet, credit card holder, or pocket. Small in size and shaped like a regular credit card, a credit card knife is a practical and portable alternative to the bulkier pocket knives you’re likely more accustomed to.

The sharp blade, compact size, and affordable price tag so characteristic of credit card knives have made them increasingly popular among survivalists. Useful while camping, hiking, and preparing food items, these knives are a really practical option.

2. What is the best knife for the money?

The budget-friendly price tag of most credit card knives means that they’re among the most affordable knives on the market. Although all of the credit card knives we have listed above are reasonably priced, the knife with the most impressive value for its quality and capabilities is, in our opinion, the Ninja Outdoorsman Credit Card Knife.

Coming in at under $10, this credit card knife boasts 11 different functions within one tool. This means you’ll be getting a practical tool that comes in handy for a multitude of purposes for a very affordable price tag. This knife comes with the promise of a full refund from the manufacturer if you’re not 100% satisfied with it, although that seems highly unlikely seeing as though over 300 Amazon users have provided an average rating of 4.7 stars out of 5!

3. Can you bring a credit card knife on a plane?

As with most sharp objects, you won’t be able to carry a credit card knife with you on a plane. However, you can put it in your checked baggage. Make sure that it’s securely wrapped to prevent any accidental injury to airport baggage handlers and inspectors.

If you forget to store your credit card knife in your checked baggage and it’s instead in your possession, you’ll be given the opportunity to voluntarily abandon it, mail it, check it, or dispose of it so take care to check it in before you travel.
