When To Use A Credit Card Knife

Say you’re walking down a dark alleyway alone and in a bad part of town at night.

That’s when someone behind you leaps from the shadows and demands you empty your pockets.

And let’s say, for the sake of example, what’s in your pockets is extremely valuable.

Maybe it is a thumb drive carrying the secrets to curing Alzheimer’s.

Or it’s the antidote for a poison that’s killing your loved one.

Whatever it is, you will not give it up so easily.

But you do not have any weapons or anything to fight with.

That is, except for your wallet knife – which you pull out of your wallet and defend yourself with.

Or, what if you become stuck in the woods?

Hopelessly lost without proper equipment. You’re out of luck.

You would be unless you happen to carry a small utility knife on you at all times!

Anthony Bourdain, the famous traveling foodie, revealed he always carries a credit card folding knife with him.

In an article about the five things he “never travels without,” he talked about it.

“If it’s a place with heavy street crime, I have this sneaky credit card that turns into a knife,”

Bourdain told the New York Times.

“It’s not something you’d want to get into a serious fight with, but it might be a rude surprise should someone grab you from behind as you enter your hotel room.”

These compact little utensils come in handy in any tight spot you might find yourself in.

Because they’re disguised, they’re so light and packable, and partly they’re just awesome.

They can be used for the following survival skills:

By carrying one, you’re more prepared for whatever tasks or challenges you may face.

How To Make A Credit Card Knife

Like many survival tools, you can, in fact, create your own.

It likely won’t be made of high-tensile, durable materials like stainless steel and polypro.

Here are a few tips and tricks to home-making your own:

1. Sharpen A Card’s Edge

The first step is to carve out the knife’s edge.

Take a used credit card (one you can’t use anymore), and mark two opposite corners with small pieces of tape.

Using a whetstone, run the edge you plan on sharpening along the stone’s length. This process will shave away some of the plastic.

Alternate which side you sharpen until the edge is evenly sharp.

Once sharpened, the edges will be razor-sharp, sharp enough to slice through paper, tomatoes, and skin.

2. Attach Things

Using tape, you can fasten fishhooks, flat arrowheads, sewing needles, etc., to the front and back of the card.

This improves your usefulness by making it a survival multi-tool.

Get creative with what you attach! If it’s small and useful in a pinch, do not hesitate to stick it on there.

3. Incorporate Cordage

With a small file, you can make a couple of notches on opposite ends of the card.

Those notches allow you to wrap a length of cordage or fishing line around the card.

Paracord is highly useful and should always be part of your survival gear.

Check out this article on paracord survival bracelets and this one on paracord uses for survival.

4. Add a Ruler

Along the edge that’s not sharp, mark out inches and centimeters with a sharpie.

This is an easy way to ensure you’ve got a small ruler on you and a survival knife.

Each should have about three inches of space for this

The Downside of DIY

Unfortunately, most homemade survival weapons are not as well-made as the ones you can purchase.

Also, with homemade credit card knives specifically, the blade is outward facing, which can damage your wallet or pocket.

And since the cordage is wrapped around the card, there can be some issues fitting it into a wallet.

Even so, they are simple to make and made of minimal, cheap materials.

You could easily make a bunch of these as homemade survival gifts.

And beyond making good gifts, knowing how to make a multi-tool is always useful survival knowledge.

The Legality Controversy

Since they are technically considered “concealed” weapons, the legality of carrying such a knife is tricky.

↓ Real Lawyer Looks At Whether “Credit Card” Knives Are Legal In Canada

In some countries, like Canada, such knives are illegal.

According to Canadian officials,

“These weapons have no other function that we can think of other than a dangerous purpose”.

That means you must be extra careful where you carry such a knife or multi-tool.

It could become confiscated, or you could be charged with carrying a prohibited weapon.

Luckily, purchasing, owning, and carrying such a knife is legal in America.

However, it’s still a prohibited item, according to the TSA.

So, even if you’re flight is domestic, you likely won’t get through airport security with it.

Thankfully, you won’t get charged for owning something illegal.

But they will confiscate the item if they see it in your wallet, bag, or pants pocket.

One TSA officer explained that finding these concealed plastic knives is not a hard thing to do:

“It’s actually fairly easy because the design of the blade is such that when it comes through we can see the blade and know exactly what it is.”

So, don’t try any funny business.

Unless you’re traveling by car, horse, or foot, leave your card knives at home with your survival gear.

Otherwise, you risk having it confiscated. Or worse, getting a ticket for carrying a “concealed weapon” in a federal facility.

I also wouldn’t recommend carrying them around in zero-tolerance zones such as school grounds.

Final Thoughts

It’s a survival tool that’s easy to your tactical wallet, bug-out bag, get-home bag, or survival first aid kit.

The bottom line is:

These knives are useful gadgets to add to your everyday carry gear.

Credit card knives are a clever, stealthy way to increase your survival capabilities.

They offer compact, light, packable, concealable survival tools.

Useful for self-defense, survival in the wilderness, and day-to-day utility.

Owning one improves your capacity for survival.

So why wouldn’t you add one to your armory?

You absolutely should.
