10 Best Keychain Tools

The best tool is the one you have with you, so what better place to have it stashed than on your keychain? Whether you need to tighten a screw, uncap a beer bottle, pry something open, tighten a fitting on your bike, or even start a fire, there’s a keychain tool for everyone.

When it comes to shopping for a keychain tool the criteria are pretty straight forward. You want a product that is light, durable, actually fits in your pocket, and, ideally, has no pieces that can come off and get lost in your daily travels. With that in mind, we’ve selected a wide variety of keychain tools for your perusal that won’t weigh you down but will help you with small day-to-day tasks.

Simple & Solid-State: Gerber Shard

The Gerber Shard features a bottle opener, small pry bar, wire stripper, three screwdrivers (a Phillips and two flat heads), a lanyard hole, and the entire thing is stainless steel with a titanium nitride coating. It’s a beloved little keychain accessory, so popular, in fact, that there’s a thriving knockoff market.

If you prefer your keychain tools to be lightweight and removable, the carabiner-style release on the Nite Ize DoohicKey makes it the one to beat.

If you like your keychain tools to look like, well, a key, then the Nite Ize QuicKey is your pick. What it lacks in wrenches it makes up for with a low profile key-shape design that is a small prying tool with a flat head screwdriver no the end, a bottle opener, and a serrated three-tooth edge that is surprisingly effective at cutting through tape, twine, and zip ties.

Sometimes you need more than a few handy tools. Sometimes you also need a flashlight. Luckily, the Swiss+Tech 6-in-1 multitool offers just such a perk! It sports a variety of screwdrivers—including a flathead, Phillips Number 1, Phillips Number 2, and 5/32-inch Allen drivers. The body of the gadget even doubles as a storage compartment for the other screwdriver bits.

Of course, it also features two LED lights, which are perfect for lighting up a dim area. And with a magnetic socket and a push-button for the flashlight, it’s super easy to use. It requires two CR1025 batteries to work, which are included.

All-A-Round Useful: Snowflake Multitool


The 18-in-1 snowflake multitool in silver and black

It can be used as a bottle opener, box opener, hexagonal wrench (3-9mm), Allen wrench (7-16mm), Phillips screwdriver, slotted screwdriver, and more. It weighs three ounces and measures 2.5 inches, and comes in a set of two so you’ll have a backup in case you lose one.

Mini, but Mighty: Leatherman Micra


The Leatherman Micra keychain multitool fully expanded

For the multitool devotees on your shopping list, there’s probably not a better pick than a Leatherman Micra (the tiny keychain version of the classic Leatherman). A small penknife, nail file and cleaner, multiple screwdrivers (two flat heads and a low-profile Phillips), a bottle opener, are all tucked inside a body that closes, just like the original full-size Leatherman, around a pair of scissors.

Simply Iconic: Victorinox Swiss Army Classic


The Victorinox Swiss Army Knife semi-expanded

We can’t very well talk about classic pocket tools without mentioning the Swiss Army knife. Victorinox’s Swiss Army Classic pocket knife is available in an updated form where the red plastic body is replaced with their “Alox” metal sheathing. The end result is a much slimmer pen knife with the same small blade, nail file/screwdriver, and scissors you’d expect.
