This Wallet-Sized Multitool Claims 60+ Functions, Here’s the Catch

A full-size multitool is useful right up until you decide it is too bulky to carry. That is the everyday problem behind the MRF Universal 3.0. Instead of packing pliers, folding blades, and screwdrivers into another chunk of metal for your pocket, MRF puts dozens of claimed functions into a card measuring 85 × 54 × 2 mm.

Price: $47.95
Where to Buy: Amazon

Sixty-plus functions sounds like a lot for something that fits in a wallet. But that does not mean 60 separate physical tools. Openings, edges, scales, and surfaces can each serve more than one purpose. The Universal 3.0 is less a miniature toolbox than a metal template for small, unexpected jobs.

More Than a Bottle Opener

Many wallet multitools offer a bottle opener, a few wrench openings, a screwdriver edge, and perhaps a blade. The Universal 3.0 goes further, combining metric and imperial wrenches, drivers, cutting edges, measuring scales, and other features in one flat piece of metal.

Its less familiar functions include a sundial compass, gauges, and a survival-oriented section that MRF says can be used for tasks such as digging or making a makeshift axe. Those descriptions need perspective: an 85 mm card is not a substitute for a shovel or hatchet.

The same restraint applies to its wrench openings. A card offers little leverage compared with a conventional wrench, so this is a tool for light, improvised work, not stubborn fasteners or jobs you could prepare for with the right equipment.

The listed firestarter function also needs an accessory: a separate ferrocerium rod. The card can act as the striker, but it is not a complete fire-starting kit on its own.

Titanium or Hardened Steel?

MRF sells the Universal 3.0 in Grade 5 titanium and hardened 440C stainless steel. Both share the same basic dimensions and tool layout, but they differ in weight and hardness.

MRF lists the titanium version at 28 grams and 35–37 HRC. Its current specifications put the 440C version at approximately 42 grams and 52–54 HRC, with raw and Cerakote finishes available. The company says the cards are laser-engraved and manually polished.

Titanium is the lighter option for everyday carry; the 440C card is made from a harder material. Those specifications help distinguish the versions, but they do not prove that either will cut better in every situation or withstand more torque at every opening.

That matters because the card’s shape imposes limits regardless of material. Its wrench openings have a short handle. Its screwdriver edges lack the reach and grip of a dedicated driver. And its cutting system does not turn it into a full-size outdoor knife.

What the Claims Don’t Tell You

The Universal 3.0’s long feature list tells you what the card is designed to do, not how well every function will work. Its small size limits grip and leverage, especially for the screwdriver and wrench openings.

MRF says some early Kickstarter backers complained about the finish on initial units and that it later improved its finishing process. The tool has moved beyond its first production run, but its 60+ functions are still best understood as backup options, not replacements for dedicated tools.

The Blade Limits Where It Goes

The Universal 3.0’s cutting edge makes it useful for opening packages or cutting cord. It also makes the card easy to forget about in the wrong place: fitting in a wallet does not exempt it from restrictions on bladed tools.

MRF positions its bladeless Universal 4.0 as the more travel-oriented option. Even so, “bladeless” is not a promise that a tool will be permitted through every security checkpoint. Check the rules before carrying either model into an airport, courthouse, workplace, or venue with tool restrictions.

For a product designed to stay with you until it is needed, that limitation may matter more than the difference in weight between its two materials.

An Established Model, Not a Prototype

MRF launched the Universal 3.0 on Kickstarter in 2017. The campaign drew 745 backers and raised $26,684. The model remains in MRF’s lineup and is available to buy rather than awaiting an initial crowdfunding production run.

That history does not establish how long an individual card will last. It does, however, make this a different buying proposition from a multitool that exists only in renderings and campaign promises.

Who Is It For?

The Universal 3.0 makes the most sense as a backup for someone who wants a few useful options on hand without carrying a conventional multitool. A wallet, compact kit, or vehicle kit is a better fit for its strengths than a planned repair job.

Choose titanium if lower carry weight is the priority. Consider the 440C version if you prefer its harder material, while keeping the card’s limited grip and leverage in mind. Neither version replaces proper pliers, a comfortable screwdriver, a full-size wrench, or a dedicated knife when you know those tools will be needed.

The 60+ functions claim is a reason to look closer, not a reason to buy on its own. The better argument is that the Universal 3.0 puts a range of small problem-solving options into a space you can realistically carry. It is not the toolbox for work you planned. It is the backup toolbox for the problems you didn’t.
