This is the kind of thing you tuck into your wallet and forget about — until you actually need it. The size of a standard business card at 3.75″ x 2″, it carries 11 separate functions in a flat stainless steel card that adds almost nothing to your wallet. I’ve looked at a lot of wallet tools, and this one packs in more genuinely useful functions than most of them.
At 0.04 inches thick, this card doesn’t add meaningful bulk to your wallet. That’s the thing I kept coming back to when comparing wallet multitools — most of them make compromises on thickness that end up making your wallet noticeably thicker. This one doesn’t. It’s 0.04 inches, which is essentially nothing.
The 11 functions cover a surprisingly practical range: a can opener that actually works, a flathead screwdriver, a ruler marked in both inches and centimeters, a bottle cap opener, multiple wrench sizes for common nuts and bolts, a saw blade, and a knife edge. The direction ancillary indicator is a simple navigation reference. The keychain hole means you can attach it elsewhere if you’d rather not keep it in your wallet.
This is a good fit for anyone who wants a genuine utility tool that lives in their wallet permanently. Hikers and campers who want a backup option without adding weight. Travelers who want tools in carry-on luggage without carrying a full multi-tool. People who just want to be the one in the office who can open the can of soup nobody brought a can opener for.
It’s also practical as a backup tool — something in your bag, car, or desk drawer that’s just there when you need it. At $4.95 and 0.1 lbs, it’s easy to keep one in multiple places without thinking about it.

The included function reference card maps out each feature, which is worth keeping. Here’s what you’re actually working with: a can opener with a functional hook design, a 1.25″ knife edge for cutting cord or scoring materials, a slotted/flathead screwdriver tip, a ruler along one edge, a bottle cap opener, a 4-position wrench that handles common bolt sizes, a wing nut wrench for hand-tightened fasteners, a small saw blade for wood and soft materials, a direction ancillary indicator for basic navigation reference, a 2-position wrench, and a keychain/lanyard hole at one end.
The stainless steel construction handles everyday use without issues. It won’t rust in a wallet or bag, and the edges stay functional with normal use. The leatherette pouch keeps it from scratching other cards in your wallet and gives you a dedicated spot to store it when it’s not in your wallet.
One thing to be aware of: like any bladed tool, this is subject to TSA rules. The knife edge is 1.25 inches, but TSA prohibits all blades in carry-on luggage regardless of size. Pack it in checked baggage when flying.

Eleven functions in a wallet card that weighs 0.1 lbs — one of the better “just keep it in your wallet” tools I’ve come across at this price point.
Yes. At 3.75″ x 2″ x 0.04″, it fits in any standard card slot. The 0.04″ thickness is roughly comparable to two or three credit cards stacked together — you won’t notice it’s there. It comes with a leatherette pouch that protects your other cards from being scratched by the edges. Most people slip it into a card slot or the cash pocket and leave it there.
In practice, the bottle cap opener, flathead screwdriver, and ruler get used most often by most people. The can opener is surprisingly functional for its size — it’s not as fast as a dedicated opener but it works. The wrench functions are useful for anyone who works with mechanical equipment or bikes. The function reference card that comes included helps you identify all the less obvious features, which is worth keeping nearby the first few weeks.
No. TSA prohibits all blades in carry-on bags, regardless of length. Even though the knife edge is only 1.25 inches, it needs to go in checked baggage when flying. It’s a good idea to move it to your checked bag before heading to the airport — or keep a dedicated one in your travel bag that you remember to check rather than carry on.
It’s a simple navigation reference etched into the card — essentially a basic compass rose or directional marker that can be used as an orientation aid. It’s not a functioning compass with a needle; it’s more of a reference tool for rough directional orientation. For actual navigation needs, a proper compass is more reliable. But as one of 11 functions on a card this thin, it’s a useful addition for outdoor use where you want a basic reference.
