How to choose the best multitool: pliers, locks, steel and what to skip
A multitool is only as good as the four tools you actually use. Here is how to judge pliers, blade locks, steel and carry size before you buy.
By OUTROOM Field Desk · Updated
Key takeaways
- Most people use four functions: pliers, wire cutters, a blade and a screwdriver. Buy for those, not for the tool count.
- Locking blades and drivers are the single biggest safety and usability upgrade.
- Stainless steel resists rust; harder blade steels hold an edge longer but need more care.
- Full-size tools (around 4 in closed) suit work and camping; compact ones suit everyday pocket carry.
A 30-in-1 claim looks great on a box. In practice the tools you reach for again and again are the pliers, the wire cutters, a knife blade and a flat or Phillips driver. A good multitool does those four jobs well and lets the rest ride along.
/ Start with the pliers
The pliers are the heart of a butterfly-style multitool. Close them and hold them to the light: the jaws should meet along their length with no gap at the tip. Replaceable or hardened wire-cutter inserts keep cutting cleanly after the first tough job.
/ Locks are not optional
A blade or screwdriver that folds under pressure is how knuckles get cut. Look for liner locks, frame locks or a lock button that holds every outside tool open, and that releases without having to push a finger in front of the blade.
| Compact / keychain | Mid-size | Full-size | |
|---|---|---|---|
| Closed length | 2-3 in | 3-3.75 in | 4-4.5 in |
| Weight | 1-3 oz | 4-6 oz | 7-10 oz |
| Pliers | Light duty or none | Everyday tasks | Real work, twisting wire, pulling staples |
| Best for | Keys, bag | Pocket everyday carry | Work belt, truck, camping |
/ Steel, in plain terms
- 420HC and similar stainless: tough, easy to sharpen, very rust resistant. The right choice for most people.
- Harder stainless steels: hold an edge longer, take a little more effort to sharpen.
- Titanium or anodised handles: lighter, but the tools inside still matter more.
/ Keeping it working
- 01Rinse grit outWarm water and a soft brush clear sand and sawdust from the pivots.
- 02Dry completelyOpen every tool and let it air dry before folding it back.
- 03Oil the pivotsOne drop of light oil per pivot, worked in and wiped off.
/ Frequently asked
What is the best multitool for everyday carry?+
A mid-size tool around 3.5 in closed with locking blades, good pliers and one-handed access. It fits a pocket and still handles real jobs.
Can I take a multitool on a plane?+
Not in US carry-on luggage if it has a blade. Pack it in checked baggage.
Is a multitool better than a pocket knife?+
If you need pliers or drivers, yes. If you mostly cut cord, packaging and food, a pocket knife is lighter and simpler.
