How to Choose a Multi-Tool: A Practical Buying Guide
Ask ten people which multi-tool they carry and about half will name something that is sitting in a drawer at home. The number of functions printed on the box turns out to be a poor predictor. What really decides whether a tool earns its place is a shorter list: weight, the plier head and how fast you reach the blade.
Start with the pliers, not the tool count
The plier head is the one part you cannot replace with something else in your pocket. Almost every other function on a multi-tool has a dedicated alternative that does the job better, so look at the jaws first. Needle nose jaws reach into engine bays and electronics. Blunter jaws grip nuts and pipe more securely. Then check the wire cutters. Replaceable cutter inserts are worth paying for, because that is the part hard wire chews up, and on a tool without them it usually ends the tool's working life.
Some makers gear the plier head. The SOG PowerLitre uses a geared rim that multiplies what your hand puts in, so you get more bite without a bigger body. It carries 17 locking tools at 130 g and fits a proper corkscrew, which is rarer on a multi-tool than you would expect.
Weight is the honest filter
This is where most buying decisions quietly go wrong. A Leatherman Skeletool CX weighs about 142 g and vanishes in a jeans pocket on its removable clip. A Wave Plus is 241 g, which for most people means a belt sheath. A Surge is 335 g and is really a tool box or vehicle item.
None of those numbers is wrong. The only question is which one matches how you actually leave the house. If you carry a bag every day, the heavier tools stop feeling heavy. If you do not, be honest with yourself and go light. A 142 g tool you have on you beats a 335 g tool you left at home.
Outboard blades and locking tools
On older designs you had to unfold the whole tool to reach the knife, which is slow and clumsy with a parcel in your other hand. Outboard blades fixed that. The Wave Plus carries two of them, one plain and one serrated, both opening one handed from the closed tool. It also locks all 18 functions, which matters the moment you lean on a screwdriver or push a saw. A tool folding back on your fingers is the classic multi-tool injury.
One note for Austria and Germany. A one hand opening locking blade counts as a knife even when it is bolted into a plier tool, so the usual carry rules apply to it. That is a subject of its own and not legal advice, so check the current rules where you live.
Bits, drivers and what you can service later
A 1/4 inch hex bit driver turns a multi-tool into a small tool kit. Bits cost little and you only carry the two or three you use. Fixed screwdrivers are simpler with nothing to lose, but you are stuck with the maker's sizes.
The Boker Plus Specialist Pro sits firmly in the workshop half of this. Spring assisted combination pliers with a reinforced, replaceable wire cutter, plus a plain blade, wood saw, file, awl, Phillips and flat drivers in a stainless handle with pocket clip and nylon belt pouch. Serviceable parts are a good sign in general. The Leatherman Surge, for example, takes an interchangeable saw and file.
Blade steel on a multi-tool
Do not expect super steels here, and do not need them. 420HC is the workhorse. It is not the hardest, but it resists corrosion well and comes back quickly on a stone, which is what you want in a blade that gets wet and gets used for jobs a knife should not really do. 154CM, used on the Skeletool CX, holds an edge noticeably longer and is the sensible upgrade if you cut a lot. Both take a fine edge. They just ask for different sharpening intervals, and both are easy to keep up with our knife care and sharpening gear.
Going outdoors changes the list
If the tool is meant for hiking, fishing or the hunting season, the useful extras are not more screwdrivers. The Leatherman Signal was built around that idea: 19 tools including a ferrocerium fire starter rod, an emergency whistle, a diamond coated sharpener and a hammer face, alongside a one hand 420HC blade and an awl. 212 g, 11,5 cm closed. Our survival multitools and outdoor tools cover the same ground.
Looking after it
Rinse it after salt water or tree sap, dry it properly, and put a drop of oil on the pivots and into the plier joint every few months. Never the dishwasher. Gritty action is almost always dust in the joints rather than wear, so flush it out first. And keep the blade sharp for the same reason you keep a kitchen knife sharp. A dull edge slips.
The short version
Pocket every day and nothing heavy: Skeletool CX. One tool that handles most of it: Wave Plus. Light body with strong pliers: PowerLitre. Workshop, van or a lot of screws: Specialist Pro or the Surge. Weekends outdoors: Signal.
