How to Make a Credit Card Knife on Your Own?

If you are a DIY enthusiast, you would be happy to know that you can make your credit card knife if the market models fail to appeal to you.

Okay, let’s make your task easier. It is not necessary to use durable and highly tensile build materials such as polypro and stainless steel. You can yet end up making a reliable knife.

There are just two main steps to create this knife. Here are the steps to perform at home for making a credit card knife on your own:

  1. Carve the Edge: This is the first step to make your own small knife. For this, just take any used or expired credit card and use a tape to denote two opposite corners. Then, with the help of a whetstone, sharpen the edge by running along the stone’s length. Doing so will remove some plastic from the card. Switch to another side for sharpening only once the initial edge for sharpening becomes evenly sharp. At this point, you need to be careful. This is because the edge you just sharpened is now razor-sharp; it can easily cut tomatoes and paper.
  2. Add More Tools: With the help of tape, it is now time to add sewing needles, arrowheads, fishhooks, and other tools to the rear and front of the card. This makes your credit card knife handier, as it is now a survival multi-tool. You can be as ingenious as possible to go ahead with what you can affix. If you have a file, use it to make some notches on the card’s opposing ends. Using the notches, you can wrap a strip of cordage around the card knife. Having a paracord is beneficial and is usually a part of most survival arsenals. You can even creatively add a ruler. Just mark the centimeters and inches along the non-sharp edge with the help of a sharpie. It then acts as a small ruler. Ensure that the card has around a space of three inches for this tool.

While it is easy to make a credit card knife, there is a major limitation. Most homemade survival knives will be incomparable to those available in the market. This is also applicable to credit card knives.

Moreover, in the case of DIY credit card knives, the blade faces outward due to which there is a risk of pocket or wallet damage. If there is wrapped cordage, you may face a few issues with regards to pocket or wallet fitting.

Overall, they are easy to design using minimal supplies. You can make a few credit card knives as family survival gifts. Apart from making such gifts, knowing how to make a multi-purpose tool is always useful.

Is It Legal to Carry a Credit Card Knife?

As credit card knives are technically concealed tools, the legitimacy of carrying it is not that straightforward.

In nations such as Canada, these knives are unlawful. This is because Canadian officials believe that these tools have no other function other than that of threatening. Thus, you should be careful when you wish to carry a credit card knife outside your neighborhood.

You should even find out whether the local laws do not ban carrying or using these knives. Otherwise, the knife could be sized, or you may become liable to pay a penalty for carrying a banned weapon.

The good news for you is that it is legal in the US to buy, own, use, and carry a credit card knife. Nevertheless, the Transportation Security Administration (TSA) considers a credit card knife as a banned tool.

What this means is that you will not get through the airport security if you are carrying this knife even on a domestic flight. While traveling by air, just keep in mind that your pockets will be checked.

Luckily, you will not be charged for having this knife. However, the officials at the airport will seize the knife if it is found in a wallet, pocket, purse, or bag.

Remember, it is easy to find these plastic knives. This is because of its small size and blade design, the latter being such that when it comes out, it is easy to see it and know what the product is.

In 2013, for a short period, the TSA had removed its prohibition on small knives. However, due to intensive opposition to it, the ban was restored.

Thus, do not give any try to carry to the airports. Keep your credit card knives at home if you are not traveling by road or on foot. Or else, you will be at the risk of confiscation or obtaining a ticket for having a concealed tool in a federal area.

In short, knives are looked upon as weapons, regardless of the size and make. Thus, it is better not to carry knives in areas where they are likely to be banned. Even if you are visiting a federal building such as a court, do so without keeping any knife in your pockets.


A credit card knife is a smart, stealthy way to boost your confidence and improve your survival abilities. It is a compact, portable, light, affordable, and concealable tool used for self-defense, survival in the wild, and daily utilities.

Owning it simply gives a boost to your survival ability. This is enough to make you add this knife to your arsenal. Go for it if you need a small EDC knife that you can carry to perform a myriad of useful jobs. However, just be careful of not carrying or using it in the prohibited or restricted regions.

Although a credit card knife cannot substitute a full-sized survival or tactical knife, it is worth having it in your wallet or purse.
