Best Credit Card Knife Reviews – Choosing One in 2018

The name credit card knife is a giveaway in itself, as it suggests that this kind of knife is shaped like the card you slip inside your wallet. What most people don’t realize, though, is that it is one of the most practical types of knife that they can have as it can be counted upon for low-key chores in the kitchen and outdoors like slicing through hardboiled eggs or cutting soft vegetables and fruits.

Another thing that you’ll love about a credit card knife is its price. For a measly amount, you’ll have a pocket-sized knife that can come in handy anytime. Of course, it can also serve as a self-defense weapon.

You should just be careful in carrying a credit card knife as it can get you in legal trouble.

Shopping for a credit card knife can be confusing what with the many models that you can choose from. But the process should become a lot easier if you opt from any of the following knives:

Boker Plus 01BO010 Credit Card Knife

Editor Rating:

This credit card knife is a mere 5 inches in length with a weight of 1.1 ounces. To give you an idea, the knife’s thickness is comparable to three credit cards stacked together. When folded, the knife is about two-thirds the size of a credit card.

The blade is a little over 2 inches long. It’s pretty sharp, capable of doing basic cutting tasks. It comes with a limited lifetime warranty.

The main beef that users have with this credit card knife is that it can be difficult to open and close. Moreover, they say that the belt/money clip is also tough to remove.

Raptor 10 in One Credit Card Tool

Editor Rating:

As its name suggests, you’re not only getting a knife in this tool. It also has a bottle opener, screwdrivers (small and large slotted), compass, magnifier, tweezers, toothpick, ruler, and position wrench.

The knife is sharp and sturdy, as well as the screwdrivers. Many users, however, agree that the compass and magnifier are both useless. Still, you’d want this tool in your bag for a camping trip. Simply put, this is a great, handy tool to buy or a good present for your best buds.

SOG Specialty Knives & Tools SOGAC77

This is another great credit card knife to have in your wallet. The blade, measuring 2.75 inches, is made of VG-10 steel imported from Japan. There should be no problem opening the knife with its ambidextrous Arc-lock. Its handle is ergonomically contoured and well-balanced, so you won’t have any issues with handling and control.

While it has its pros, you will have to understand that it has its shortcomings, too. One is that the clip is a bit small that it makes sliding the knife into the pocket quite difficult. Plus the price is a bit high. Overall, this is still a solid choice for a credit card knife.

Tool Logic CC1SB Credit Card Companion 

Editor Rating:

Like the Raptor 10 in One, this is a credit card knife with multiple tools. You get a bottle opener, compass, toothpick, ruler, tweezers, a serrated blade, and power lens. But the key feature is still the 2-inch stainless blade that is sharp enough to cut through the toughest materials.

While it does have numerous implements, this credit card knife doesn’t have the best of features. Many users think that the compass doesn’t point anywhere consistently, and the plastic tweezers are pretty much useless.

Iain Sinclair Cardsharp 2

Editor Rating:

When it comes to design, only a few in this list can match up with the ingenious design of this Ian Sinclair product. It ‘transforms’ from a knife into a card in just three folds. It is also slimmer and lighter compared to a traditional knife. Its polypropylene body ensures longer shelf life, while a unique safety lock prevents accidents.

You will have to deal with the flaws of the credit card knife, though, like it not being the most robust in this list.

CSync Direct Key Shaped Knife

Editor Rating:

This is a lightweight pocket knife that you would want to bring with you all the time. It’s about the size of a standard house key, but gives you multiple tools. 

Aside from the sharp knife, you get a screwdriver, a can opener, a bottle cap opener, a ruler, a four-position wrench, a saw blade, and a lanyard hole, among others.

Guardman Key Knife 11-1 Multi-Tool Card

Editor Rating:

This is another multi-tool card that includes a sharp knife for small tasks, like box cutting, opening packages, and cutting through food. 

It’s almost the size of a house key, with the blade length around 2 inches. When extended, it measures less than five inches.

Aside from the knife, you also get a bottle opener, a saw blade, a can opener, a flat screw driver, a two-position wrench, and a direction auxiliary indicator or compass.

Not all tools are useful, however. The compass, according to most reviews, is completely useless. The tweezers aren’t of good quality as well.

ACCMOR 14 in 1 Pocket Survival Card Tool 

Editor Rating:

This tool not only carries a knife, but 13 other implements as well. 

You get, among others, a bottle opener, small and big slotted screwdriver, a compass, tweezers, magnifier, ruler, toothpick, cutter, sharpening stone, fiber rope, and emergency whisper.

It’s about as thick as four credit cards. It is durable and lightweight, being made from thermoplastic resin and stainless steel. This tool just won’t bend or break.

The tools look good, but you may be disappointed by the fact that they are hard to pull out. But that is the only flaw in this otherwise excellent product from Accmor.

Yansanido 11 in 1 Credit Card Wallet Knife

Editor Rating:

Again, this is a versatile credit card wallet knife as it also comes with 11 tools that can come in handy anytime. 

The knife itself is made of sharp, solid 420 stainless steel. It’s the type of knife you would want to have when in the outdoors. It’s also good enough for everyday use. The two-inch serrated edge blade won’t have any problem cutting through the toughest materials.

While it is very cheap, the credit card wallet knife isn’t perfect. Many users say that its other implements aren’t as tough as the knife itself.

I Survive Pocket Knife Credit Card Companion Survival Kit with 9 Essential Tools

Editor Rating:

Weighing just 1.5 ounces, this is a lightweight and versatile tool that you also want in your wallet. Its key tool is the razor sharp, two-inch steel blade that is good enough for everyday cutting tasks.

Moreover, it has eight other essential tools that will come in handy anytime. It has a bottle opener, ruler, position wrench, magnifier, small and large slotted screwdrivers, and tweezers. Keep one in your bag or car for your next camping or hunting trips.

What to Look for in a Credit Card Knife

With the many kinds of credit card knives that you can find in the market, you might get confused on which type to get. One thing you might want in a credit card knife is a good locking mechanism. This would prevent accidental cutting whenever the knife is closed. Moreover, look for a credit card knife that has a built-in sheath to keep the blade protected against dust and other elements.

The blade is something you should also be concerned with. There are different materials used for the blade. You can go for a Teflon glazed blade which is known for longevity, or a stainless steel that can resist corrosion.

Credit card knifes can have single or multiple blades. A single blade folding knife is best used for heavy duty tasks. Those that feature multiple blades are more suited for everyday use, like slicing an apple or cutting envelopes.

You’d also want a credit card knife that has a fastening system, capable of a quick release. Plus, you will definitely prefer one that is lightweight enough to be inserted in your wallet.

The handle is equally important. If you have a limited budget, you can go for a plastic or rubber handle. The downside is that the handle likely won’t last long. If budget is not an issue, buy one made of Kydex as it offers an excellent grip and control.

It would help, too, if the credit card knife has other tools like bottle opener and compass. However, you should ensure that the most important implement—the blade—is sharp enough for whatever cutting task you may need to accomplish.


Now that you have an idea on which credit card knife to buy, why don’t you start shopping for one now?
