Best Multi-Tools for Every Carry Size: From Keychain to Beast Mode

Introduction

Multi-tools come in all kinds of different sizes, and picking the right one is mostly about matching the tool to how you actually carry and use it. Some live on a keychain, some live in a pocket, and a few push the format to extremes. Here is a look at six options across that whole spectrum, from the industry-standard size down to pocket-sized gems and one absolute monster.

The Everyday Benchmark: Leatherman Wave

The Leatherman Wave is sort of the industry-standard size for a multi-tool. It is the reference point that most other tools get compared against: big enough for real work, small enough for regular pocket carry, and packed with the tools most people reach for day to day. If you only own one multi-tool, this size class is where most people land, and the Wave is the classic choice in it.

Small but Outstanding: Leatherman Squirt P4

You can go considerably smaller than the Wave. The Leatherman Squirt P4 squeezes pliers into a genuinely tiny package, and it is just outstanding for what it is. The main catch is availability: it is unclear whether it is still made anymore, so finding one may take some hunting on the secondhand market.

A Substitute for the Squirt: Gerber Vise

If you cannot track down a Squirt P4, the Gerber Vise works really well as a substitute in the same small-carry niche. It covers the basics in a compact package and is a sensible fallback if you want keychain-friendly pliers without chasing down a discontinued tool.

Going Bigger: Leatherman Super Tool

On the other end of the scale, the Leatherman Super Tool starts to get into something a little big for pocket carry. It is a decent-size tool with a large blade inside and fairly large pliers with good, solid cutters. If your work leans on cutting and heavier plier tasks more than portability, stepping up to this class makes sense.

Even Bigger and More Feature-Packed: Leatherman MUT

Bigger still is the Leatherman MUT. It has a similar front end to the Super Tool but a longer rear with more features. It is squarely in the large-tool category, so it is best thought of as a kit or belt tool rather than a pocket one. If you want maximum capability and do not mind the bulk, it fills that slot well.

The Beast: Kilimanjaro Magnus

Then there is the Kilimanjaro Magnus, an absolute beast of a tool. Before assuming that something this big must be expensive, know that it runs about $30, so it is kind of what you expect at that price. It has a fairly large plier handle, but oddly the pliers themselves are not much different from the little Leatherman Wave. The big difference is in some of the other tools, most notably the knife blade: a 4-inch blade that Kilimanjaro says has the strength and metal to perform like a real knife.

The build feels like some kind of anodized aluminum, with a controllable pivot, though there is a little bit of play. The liner lock is a great big piece of metal you have to pinch in. There is also a saw with real girth, a file carved into it, a big Phillips screwdriver, and a slotted screwdriver with a bottle opener, which rounds the tool out.

In real use it is mixed. The pliers did work when crunching and pulling hard on things, without a lot of sideways flex, though the plier mechanism is made from more pressed metal sitting in a metal sleeve, so it is not a very strong plier design. Wire cutting is marginal: it will cut stranded wire but not quite finish the cut, while solid core wire does get snipped. The saw sort of works, but it is thick and really short, almost like a bone saw, which is one of the downfalls of a tool like this.

There is an honest trust issue here: it is hard to fully trust something this big, with this many features, that costs under $30. The practical advice is simple. If you want a very large knife, buy a very large knife, and pair it with a quality multi-tool. The Magnus might be kind of fun for a teenager to play with, and it could genuinely add something to an adventure kit, but the Leatherman Wave will be way better in straight comparison.

Buying Advice

The size-first approach works well here. Get the Wave if you want the safe, standard pick. Get the Squirt P4 or Gerber Vise if keychain carry matters most. Step up to the Super Tool or MUT when you need more blade, bigger pliers, and better cutters and can accept the bulk. The Kilimanjaro Magnus is only worth it as a curiosity or a large-blade novelty at its roughly $30 price, not as a primary tool.

Conclusion

There is a multi-tool for every carry style, and the best one is the size you will actually have with you. Start with the standard-size Leatherman Wave, go smaller with the Squirt P4 or Gerber Vise, go bigger with the Super Tool or MUT, and treat the Kilimanjaro Magnus as the fun outlier it is.
