Credit Card Knife, Foldable Stainless Steel Blade, 2.75 Inch, Fits in Wallet, Blade Lock, Ultra-Thin EDC Tool for Emergency Backup and Everyday Carry

You’ve got a knife at home. Probably a good one. It’s just not with you right now—it’s in a drawer, or a junk bin, or wherever knives go to be useless. This one goes where your cash goes.

Who this is for: the person who won’t carry a pocket knife because it prints through their jeans or feels like overkill for opening mail. Delivery drivers breaking down boxes all day. Parents who need to cut a zip tie out of a new toy without hunting for scissors. Anyone who wants a backup blade in their glovebox, go-bag, or desk without adding bulk anywhere.

Quick gut-check: if you’ve ever dug through three kitchen drawers looking for something sharp, or used your keys to open a package because that’s all you had—this solves that. It’s not replacing your everyday knife. It’s making sure you’re never without one, period.

Key Features & Benefits

• 2.75-inch stainless steel blade — enough edge for tape, packaging, cord, and light utility work
• Folds flat to credit card size — slides into a wallet slot like just another card
• Blade lock mechanism — holds the blade open during use so it won’t fold back on your fingers
• Ultra-thin profile — you won’t notice it’s there until you need it
• Lightweight build — adds next to nothing to what you’re already carrying

Practical Details

Legal in most states as a general utility tool, but check your local laws before carrying—some areas restrict blade length or folding mechanisms, and workplaces or schools may have their own rules. Keep it dry and wipe the blade down after use to prevent corrosion. It arrives ready to fold flat into a wallet slot—no assembly, no sharpening needed out of the box.

Five bucks is cheap insurance for never being caught without a blade. Add it to your cart and slide it into your wallet tonight—or check out the rest of our everyday carry gear built for exactly this kind of quiet, reliable readiness.

FAQ

Will this hold up to daily use?
It’s built for light-duty tasks—opening packages, cutting tape or cord, basic utility work. It’s not meant to replace a full-size knife for heavy cutting, but for the everyday stuff, it holds up fine.

Does it actually lock in place?
Yes. The blade lock keeps it extended while you’re using it, so it won’t fold shut on your fingers mid-task. Always fold it back before returning it to your wallet.

Will it damage my wallet or wear out my cards?
No. It’s designed to sit flat like a standard card, with no exposed edge when folded. Most people keep it in a spare card slot without any issue.

Is it TSA-approved for carry-on bags?
No. Like any knife, it needs to go in checked luggage when flying. Treat it the same as you would any bladed tool at airport security.
