Why Choose a Keychain Knife?

Carrying a small pocket knife with you, particularly while traveling abroad can be risky due to stringent rules and regulations. Nevertheless, it is also true that traveling without one such knife, specifically, if you will be trekking or camping, is likely to be unsafe.

Moreover, travelers will also be concerned about the weight as well as the size of things to be carried. Carrying a big blade is not only illegal but is also potentially harmful. It can even instill fear in people surrounding you.

Considering all the legal and personal issues, it is ideal to have a small, unconscious knife. The best way to do so is to invest in a keychain knife.

The tools integrated into their body include toothpicks, scissors, and tweezers. This is how the value of these knives enhances when you hang to your chain. You are likely to find yourself accessing it for one task or another quite often.

When you are outside, there is a high probability of cutting a variety of objects intermittently. While you can cut or open some by hand, the rest will require some kind of a cutting tool.

Buying Guide For Choosing The Best Keychain Knife

Different types of keychain knives can be seen in the market today. Each of them differs in size, price, and features. As a fact, no two keychain knives are identical in terms of performance. One of them is likely to be better, as per the blade, tools, and finish.

There are a few popular brands whose keychain knives come with everything that is required. Initially, it might seem a bit easy to select the best keychain knife, as you may feel like picking the most affordable as well as a visually appealing one. This is the same experience while buying a keychain.

However, buying one such knife based on these two factors can be dangerous. This is because some of these keychain knives can be irritating to use and can cause you harm if the design is terrible, and the quality is poor.

Thus, it is essential to select a keychain knife carefully by keeping an eye on the finest quality. A keychain knife of such a quality is most versatile in terms of functions it can perform. It is possible to buy such a knife by considering all the factors contributing to its overall quality. So, let’s look at them:


You will be looking for a small size that does not impose any kind of burden while carrying the knife with you. Rather, it should be comfortable for you to carry. The best keychain knife is light in weight and compact in size so that you can easily and swiftly add it to a lanyard or even a keychain.

After all, it is made to be disguised as a keychain while being carried by you. Ideally, the size should not be bulkier or bigger than a set of few keys.

Most models are approximately four inches long and become smaller when folded. The ideal weight must not be over three ounces when closed and over four to five inches while in use.

It is wise to check the customer reviews. Some reviewers share a photo too and comment on the knife’s size. This is useful!


The ideal blade has a length ranging from one to two inches. When closed, the knife length is between 0.5 and 0.7 inches. Further, it is built using a sturdy stainless steel material, as it is light and resistant to corrosion.

The material is also responsible for rendering a sharper edge that retains itself for a longer time than usual. This means you do not have to frequently re-sharpen. In case the knife becomes wet, the material resists rusting. You should wipe it dry. Look for blades made up of 420C, 3CR13, or AUS 8A stainless steel.

Considering the small size, the simplest shape for the blade is the drop point. However, you will come across other shapes, too, including the serrated ones.


The handle of a keychain knife can be made using either natural or synthetic materials. The synthetic ones are light and strong due to which they are ideal for those who are looking for a slim design.

Glass-filled nylon as a synthetic material is a perfect choice, as it is too rigid and is resistant to impact due to dents and scratches. It ensures ease of use and utmost durability.

At times, you may also find that the handle consists of stainless steel so that it becomes strong and more elegant. It is likely to be polished with a distinct look to keep the scratches and fingerprints at bay. Such handles are usually a part of the Swiss army keychain knives from Victorinox.

It is up to you to choose the handle material. No matter which one you choose, ensure that it is of good quality so that your knife tends to last longer.

Extra Tools

The branded keychain knives typically come with many attachments in the form of small tools. Most of them have a bottle opener and a key ring. However, a few also have scissors, tweezers, nail filer, toothpick, and screwdriver.

If you are going to use these tools quite frequently, it is wise to get one such keychain knife acting as a multi-utility tool. It will also save you money and storage space, as you do not have to spend on these tools separately.


Can I carry a keychain knife anywhere; is it legally okay?

Yes, for most states! A keychain knife is nothing but a small blade useful for small cutting tasks or self-defense. The blade’s small length does not trigger any legal conflicts in most regions in the United States.

Even on flight, such knives can be carried if it allowed by the airline policies. Still, it is wise to know and check the laws regarding carrying knives to ensure hassle-free traveling.

Are stainless steel blades coated?

While most keychain knife blades are composed of stainless steel, a few come with a coating. This coating makes them resistant to rust and corrosion that may happen if they remain wet. In this way, they become more durable.

Titanium is a famous coating material used to make keychain knives sturdier as well as sharper for cutting hard stuff. Just look for the product specifications to know the materials used.


Keychain knives are for those who like to stay prepared for facing any situation or are serious about survival tools. Although seeming to be small and trivial, the best keychain knife can be a treasured pal in.

When it comes to buying the best keychain knife, consider thinking about its uses and then analyze whether a promising keychain knife is capable of fulfilling those requirements or not.
