Credit Card Knife – 2.75″ Blade, Blade-Lock, Wallet-Slim

Most people never think twice about carrying a small blade until they actually need one. A box that won’t open, a cord that needs cutting, a package that arrives wrapped in layers of tape—a basic cutting tool solves all of it in seconds. The Credit Card Knife is a 2.75-inch folding blade sized to fit in a wallet slot, so it’s there when those moments come without adding bulk or weight to your carry.

Who This Knife Is For

This knife is a practical choice for people who want a compact cutting tool they’ll actually have on them. That includes commuters and office workers who open packages regularly, campers and hikers looking for a lightweight backup blade, and anyone who’s had a moment where a small knife would have been genuinely useful. It’s also a reasonable option for a travel bag, glove box, or emergency kit where space is limited. If you’re looking for a primary work knife or a blade for demanding outdoor tasks, this isn’t that—and it doesn’t pretend to be.

Is It the Right Fit for You?

Choose It If You Want

• A blade that fits in a wallet slot and adds virtually no profile
• A locking mechanism that keeps the blade secure whether it’s open or closed
• An affordable backup cutting tool for a bag, glovebox, or travel kit
• Something lightweight—0.1 lbs—that you genuinely won’t notice carrying

Consider Another Option If You Need

• A longer blade for heavy-duty cutting or outdoor field work
• A fixed-blade knife for tasks that put sustained stress on a hinge
• Multiple tools in one—a compact multi-tool may serve you better

Credit Card Knife Features and Benefits

• 2.75-Inch Steel Blade: Long enough for most everyday cutting tasks—opening boxes, slicing cordage, trimming material—without being oversized for wallet carry.
• Blade-Lock Safety: Holds the blade securely in both the open and closed positions. It won’t deploy accidentally in your wallet, and it stays in place during use.
• 0.13-Inch Profile: At 3.38″ x 2.13″ folded, it fits a standard wallet slot and sits flatter than most multi-tools.
• Lightweight at 0.1 lbs: Light enough that it genuinely doesn’t change the feel of your wallet or bag.
• Disguised Form Factor: Looks like a card at a glance. Useful if you prefer a low-key carry option.
• Black Finish: Clean, neutral appearance that doesn’t stand out.
• Everyday-Carry Utility: Sized and priced to keep in multiple places—wallet, bag, glovebox, travel kit—so you’re not relying on one knife being in the right spot.
