A compact folding knife that stores flat like a credit card and unfolds into a functional blade when needed. The 2.75-inch steel blade locks securely in both open and closed positions, and the entire unit fits in a wallet, pocket, or bag without adding bulk.
- Credit Card Form Factor – Measures just 3.38″ x 2.13″ x 0.13″ when folded flat
- 2.75-Inch Steel Blade – Surgically sharp edge for everyday cutting tasks
- Blade-Lock Safety – Secure locking mechanism prevents accidental opening
- Ultra-Lightweight – Weighs only 0.1 lbs, virtually unnoticeable in a wallet
- Simple Deployment – Pop the blade-lock and fold into a usable knife in seconds
- Low-Profile Black Finish – Discreet appearance that blends with wallet contents
Most people carry a wallet every day. Very few carry a knife, even though a small blade is one of the most universally useful tools you can have on hand. The credit card foldable knife bridges that gap — it fits where your cards go and unfolds into a working knife when you actually need one.
Who This Knife Is Best For:
- Everyday carriers who want a compact utility blade without the bulk of a traditional pocket knife
- Outdoor enthusiasts who need a lightweight backup cutting tool for camping, fishing, or hiking
- People who frequently open packages, cut cordage, or handle minor cutting tasks throughout the day
- Gift buyers looking for a practical, conversation-starting accessory at an affordable price point
Is This the Right Knife for You?
Choose the Credit Card Foldable Knife if you want:
- A knife that fits in your wallet and adds virtually no weight or bulk
- A locking blade for safe handling during basic cutting tasks
- An affordable backup blade you can keep in a bag, glove box, or emergency kit
Key Features: The blade is 2.75 inches of quality steel with a surgically sharp edge, adequate for most everyday cutting tasks — opening boxes, cutting zip ties, slicing cordage, or preparing kindling. When folded, the entire knife compresses into a form factor that measures 3.38 inches by 2.13 inches and just 0.13 inches thick. That is thinner than most multi-tools and barely thicker than an actual credit card.
The blade-lock mechanism is the detail that separates this from novelty items. When closed, the lock keeps the blade seated so it will not deploy accidentally in your wallet or pocket. When open, the lock holds the blade in position so it functions like a proper folding knife. It is a straightforward design that does what it is supposed to do without unnecessary complexity.

Frequently Asked Questions
Will this knife set off a metal detector?
Yes. The blade is steel, and it will be detected by standard metal detectors. This is not designed to bypass security checkpoints. Do not carry it into restricted areas such as airports, courthouses, or government buildings.
How sharp is the blade out of the box?
The blade comes surgically sharp and ready to use. Like any knife, the edge will dull over time with use and can be maintained with a fine sharpening stone or ceramic rod.
Is this strong enough for heavy-duty cutting?
This is designed for light to moderate everyday tasks — opening packages, cutting string or tape, slicing fruit, and similar uses. For heavy-duty cutting, a full-sized folding knife or fixed blade would be a better choice.
