Types of Keychain Multitools

One-Piece Multitool

Keychain multitools like the Gerber Shard Keychain Tool and the CRKT Eat'N Tool Outdoor Spork Multitool are basic gadgets that are very slim and streamlined. They fit easily alongside a set of keys and are somewhat unobtrusive. They are, however, limited in the number of functions they provide and sometimes focus on specific activities, such as bicycling or camping/backpacking. They consist of a single piece of steel.

Folding Multitool

If you're looking for a multitool that has a straight-edged knife and a variety of other tools, such as spring-loaded scissors, tweezers, etc., that fold closed when not in use, then your gadget is going to be a bit heavier and bulkier than a minimalist option. The upside is that you will typically have more tools at your disposal, but the downside is it will take up more space in your pocket.

Top Brands


When you think of pocket knives, you think of Swiss Army knives, which are made by Victorinox. Based in Switzerland, this company was founded in 1884 and has been making knives for over 130 years, including its popular multitools, many of which can be easily attached to a keychain. We recommend the Victorinox Tinker Tool.


Navy veteran Josh Downes founded Keyport 15 years ago. Based in Las Vegas, Nev., the company produces devices that merge keys, tools, and more to make practical everyday carry items that are universally accessible. One popular product is the Keyport MOCA Tool.


Gerber, based in Portland, Ore., was founded in 1939 and produces popular knives and other gear used by hunters, soldiers, and more. The company is known for backing its products with lifetime warranties. One top multitool is the Gerber Dime Mini Multi-Tool.


Timothy S. Leatherman and Steve Berliner founded Leatherman in 1983. The company, based in Portland, Ore., makes a variety of knives and multitools, including what it claims is the world’s first pliers-based multi-tool. With a boast like that, you can’t help but check out the Leatherman Squirt PS4 Multitool.

Keychain Multitool Pricing

  • $5-$15: Some keychain multitools are very inexpensive, but they may not be very durable and don't have a lot of features. If you spend towards the upper limit of this price range you can find a decent device that will last for a reasonable amount of time.
  • $15 and up: The best keychain multitools are a little more expensive. You will also find more well-known brands in the higher price range. These products are of higher quality and built to last.

Key Features


Some keychain multitools are smaller than others. If you want something that's extra portable and won't take up much space in your pocket alongside your keys, you may want to opt for a smaller, minimalist device. If the number of functions is important, you may need to choose a product that's a little bulkier and heavier.

Type and Number of Tools

Different multitools provide different functions. They may come with knives, pliers, spring-loaded scissors, bottle openers, flat and Phillips screwdrivers, tweezers, and nail files. Some are designed with functions that you may need while camping (a spork, for example). Decide what type of portable tools you need by your side before making a purchase, so it will suit your particular needs.

TSA Compliance

Do you travel frequently by plane and like having a small set of tools on hand just in case you need them? Then you should choose a multitool that is TSA compliant. However, it is up to the discretion of airport personnel, and they may still require you to check the multitool instead of carrying it on board, despite what the manufacturer says about its compliance.

Other Considerations

  • Style and Design: Are you interested in a traditional multitool in which the tools fold up into a convenient housing? Or do you want a keychain multitool that is a single piece of steel? You can also choose whimsically shaped and colorful multitools that show off your personality.

  • Make sure you know how all the features function. You may have tools available that you didn't even realize were there because you didn't take the time to identify them.
  • Properly maintain your keychain multitool to extend its service life. If possible, use lubricant or surface protectant or even WD-40 to keep it in tip-top shape. Also, make sure the knife is sharp so it will work effectively.
