Most Important Features to Consider

Knowing what aspects you should look for beforehand is always a good way to start your search for the best possible item. For that reason, we have highlighted the most important characteristics that every keychain multi tool must have.

Number of Functions

For multi tool keychains, the feature to make note of is the amount of functions the tool can offer. A basic feature for every keychain would be having a screwdriver and bottle opener, but according to your needs, you can find scissors, carabiners and so on.

Now, this really depends on your needs. Having a lot of functions is not necessarily a must because you might just end up with a tool with features you don’t need. Therefore, determine the functions you need most and start from there.


Another feature to make note of is the durability of the keychain itself, and the materials that were used to build it will tell you how long lasting it is. Most keychains are made with stainless steel but the designs can vary from one to the next. Tools that features thin steel construction is simply not going to cut it in terms of longevity and durability.

Again, this will all depend on your personal requirements. If you are going to use the multi tool for outdoor use, you will want one that can withstand a good deal of punishment, preferably those that have undergone heat treatment. Ideally, it won’t hurt to get a multi tool that will last you a long time but this also means a higher price tag.

Design and Weight

Keychains can come in different sizes, shapes and functions, so they’re not created equal in terms of shape. Also, some of them are more comfortable than others to carry, due to their shape, weight and size. Most keychains weigh under a pound, but you must have in mind that the lighter they are, the fewer functions they have.

Of course, this will again depend on which functions you are looking for. If you want to be a walking toolbox, a feature packed item might be more right up your alley. However, keep in mind that it might be heavier and more unwieldy. If you just want the bare minimum functions, there is no shortage of tools that can offer you just that.

TSA Approval

This is not actually necessary, but if you were to take a keychain multi tool to a plane, make sure it is TSA approved. If it has the approval, the item would say so in the case or on its syrface. The TSA is very specific about what you can and cannot fly with.

There’s a good chance that the TSA will confiscate your item even if it’s deemed authorized by them. If you don’t want to lose your multi tool, you might want to stash it into your check in luggage.

Carrying Method

A multi tool is only as good as your willingness and ability to carry it. One of the most important things to consider when choosing a multi tool is to determine how it can best fit in your overall lifestyle. Fortunately, you have many options to choose from.

For example, there are keychain multi tools that you can attach to your keys which allows easy and universal portability. After all, you carry your keys with you all the time, right? There are also belt multi tools that can be worn on your hip. These are usually full size tools that are designed for the most rugged jobs but not the most pocket friendly variants.
