An entire world congregates around EDC (or everyday carry items), and none is more popular, more versatile, and more sought-after than the lightweight, portable wallet card multi-tools. They make take up a small footprint, but these multi-use trinkets pack a wallop of a punch — just one rectangular piece of steel can have more than 30 different tool applications, and weigh just a single ounce.

The Best Card Tool
You need a multi-tool that you can take with you everywhere — to work, to the baseball game, out on the boat, and even through airport security. You’ve found it with the Wallet Ninja 18-in-1 Card Tool! This card multi-tool, which is just barely longer than a traditional credit card but still fits in a wallet’s credit card slot, is made from four-times heated treated steel to be strong, durable, rust-proof, and consistently sharp. The Wallet Ninja includes 18 tools in its one card size. These tool features include six hex wrenches, a can opener, a fruit peeler, a bottle opener, a ruler (which includes both standard and metric measurements), a letter opener, a box opener, a phone stand, an eyeglasses-size screwdriver, Phillips head screwdriver, and a flat head screwdriver.
Each corner of the card features a different screwdriver to fit your task at hand. What we really love is the phone stand. Simply slide one of your credit cards into the slot located near the bottom of the multi-tool. You want enough of the credit card to slip through to support the base width of your phone. The multi-tool and credit card then support themselves from the weight of your phone against the angle of their joint, and voila! You have an on-the-go phone holder. The Wallet Ninja is the definition of a “can’t leave at home” tool.

Card Tool Buying Guide & FAQ
Features to Look for in Card Tools
Size - The standard dimensions for a credit card are 3.375 inches by 2.125 inches. Nearly every credit card-sized multi-tool will fit into these dimensions to easily slide into your wallet. However, you should pay attention to the thickness of the multi-tool, in case you have very tight credit card slots in your wallet, or it’s already too thick to close effectively. Keep an eye out to see if the card tool is larger than these standard dimensions, as well. You may have to upgrade your wallet to fit your card tool!
Material - Good card tools will be made from durable, unyielding metal materials. Some may be stainless steel, some may be titanium, others aluminum. Some may thinner, but make sure that thin card tools are still made from strong materials. Other cards may be made from hardened plastics. This is certainly a cheaper option and can work well for light household jobs, but be wary of these options, as they could break under pressure — or even from sitting on your wallet the wrong way!
Additional Features - A whole world awaits those looking into credit card multi-tools. Some cards may sport a retractable knife, while others may have tiny flashlights! These features may cost extra, but they could mean all the difference in a pinch. If you’re interested in additional features, look no further — our selection includes several upgraded options for the ultimate card tool.
Card Tool FAQ
Q: What are the card tools?
A: Rather than carry around a heavy Swiss Army-type multi-tool, or keep clunky toolsets around, card tools are multi-use tools that fit in the credit-card slot of your wallet. They are generally made from durable materials like steel or titanium, which won’t bend or break with everyday force and use. However, card tools will be thin and rectangular (like a credit card) so that you can easily keep one with you at all times.
Generally, card tools will include some size of wrenches or hexes, a screwdriver tip, and a knife blade. Each card tool holds its own unique set of features, so be sure to check and make sure you like the included tools before purchasing. Card-sized tools have become exceedingly popular in EDC (or everyday carry) culture. This means you have the tools and essentials with you in your backpack or your pockets at all times. A card tool allows you to slide a handy multi-tool out of sight and out of mind until you need it most.
Q: What is a card tool used for?
A: Credit card tools are not meant to replace the toolset that you have in your shop or your garage. However, they come in handy when you’re out to dinner, and someone’s eyeglasses lose a screw, or you’re at work, and your desk starts to wobble from loose parts. Maybe you need help disassembling an office appliance, and no one has a screwdriver handy? Card tools stay safely stashed in your wallet until the time they’re needed, without taking up space, weighing you down, or hanging off of your pants pocket like a traditional multi-tool. Credit card tools are an all-in-one deal for the most common types of quick-fixes in your home or workspace.
Q: How do you use a card tool?
A: Ultimately, this depends on what tools are included in your card tool’s feature list. For the most part, The interior features (like the wrench cut-outs) work by placing the card tool over the piece of hardware you’re trying to tighten or loosen and maneuvering the piece as needed. The bottle opening features should be a no-brainer; simply set your bottle cap under the flat edge and use the rest of the metal card as leverage. Other features, like a screwdriver or blade, will be located on the outside edges of the card tool and can be used carefully by holding the entire card while you do what you need to do.
