Introduction

While many wouldn’t agree, it cannot be denied that the need for a knife can arise at any time. Whether you’re at home, traveling, or going on an outdoor adventure, the humble knife can prove to be vital and useful in a number of situations (you should not have to watch Expendables, 24, or The Hunted to figure this out!). A large number of people still look at the knife as only a weapon. But it was the first tool man ever invented.

From cutting logs to make a fire to hunting animals for food, the earliest humans did everything with these sharp tools that they made out of rocks and stones. These days, knives come in various forms. There are large knives for making mince meat and smaller ones for self-defense. You can even get knives in the form of a keychain. Though small and easy to conceal, they are highly useful.

Can they stand up against the bigger knives? Probably not, but they are useful for several purposes, from cutting open a package, to removing tags from new clothing, or defending yourself against wild cats. It weighs a little more than a keychain, and is a versatile tool to keep in your pocket.

Things to Consider When Choosing a Keychain Knife

A keychain knife is meant to look like just another set of keys in your pocket. Knife enthusiasts would love to carry their everyday carry knives everywhere, but such a prospect is highly impractical. Thankfully, technology had advanced far enough to let you carry a knife the size of a keychain. Cool!

These knives are so shockingly small that first-timers may wonder if they are of any use at all. You’ll be surprised that these knives often offer better value compared to their bigger counterparts.

There are various types of keychain knives available today. You can get one online for as little as $5. But not all keychain knives will perform the same. One will always be better than the other, depending upon the make, blade, and finish. There are some very popular brands around, and there’s a reason why they became popular. They offer everything that is desired in a keychain knife.

It might seem like an easy task to buy a keychain knife because they cost so little, but some of them can be frustrating to use and the bad ones can even slice off the top of your finger. Therefore, whether you buy a keychain knife online or from a store, several factors must be considered before purchase, from the blade, to size, to the design and cost.

Even if you buy a keychain knife online, the criteria for choosing one remains the same as when you buy one from a store. Buying a product online is a little different because you can’t hold and feel the product to ascertain the quality. To make sure you get only the best, you should buy only from known or proven brands (though this is not always the case – perhaps a new business is putting out a stellar product for a decent price – every fantastic business has to start somewhere). With that said, let’s look at the factors to consider when buying a keychain knife.

Size: A keychain knife should be no bigger or heavier than a set of keys. In fact, it is meant to be carried inside a pocket or a purse, disguised as a keychain. The size and weight of the knife is one of the first things to consider. What size will comfortably fit in your pocket or purse?

The ideal weight shouldn’t be more than three ounces, and no more than four or five inches when open. Keychain knives are capable of a lot, so you can safely by a lightweight one without worrying about functionality.

Blade: The ideal blade length of keychain knives is between one and two inches. Most keychain knives are between 0.5 and 0.7 inches when closed, and when open, the blade extends another inch or so. The blade is usually made of steel, most common being AUS 8A, 3CR13, and 420C stainless steel.

The handle is usually made from glass filled nylon for maximum durability and ease of use. Since a keychain knife is tiny, the easiest blade shape to achieve is the drop point, although there are other shapes too, such as a serrated blade. All these factors come together to make an ideal keychain knife.

Attachments: Keychain knives – especially the branded ones – usually come with a lot of attachments. Most knives come with a keyring and bottle opener, but good ones also come with a nail filer, scissors, screwdriver, toothpick, and tweezers. Yes, when you buy a good keychain knife, you get to carry a multi-utility tool with you all the time. Whether you need to uncork a bottle or need a pair of scissors urgently, having a multipurpose keychain chain is a wise idea.

Cost: How much are you willing to spend on something the size of a house key? Keychain knives come for as little as $5, and can even be as costly as $100, depending upon the brand, the build, and the attachments. If you don’t need the knife for much, then $5 knife will suffice, but if you need more functionality, then there are more expensive options.

You should not expect to obtain a high-quality knife or even an average quality knife for $5.

Top 10 Keychain Knives

Given the wide range of keychain knives available on the market, picking the right one can be confusing. There are budget options, as well as expensive ones that come with a number of attachments. Below are the top ten keychain knives.

If you’re looking for a really tiny knife that disappears in your pocket, you should be looking at the Spyderco Manbug. Spyderco is known for making multi-utility tools, but you cannot admire the Manbug enough until you hold it in your hand.

At only 0.64 ounces, this is one of the lightest, tiniest, and most portable keychain knives you can ever get. It is easy to clip onto your keychain, or let it float free in your pocket. It also locks solid, just like an EDC knife. You cannot imagine how small it is until you see it for yourself, but it’s easy to open with one hand, and also has fantastic grip. It’s like a diminutive version of a regular pocket knife.

The knife is 4.5 inches when open and 2.5 inches when closed. The blade is constructed of high-quality VG-10 steel, while the handle is fiberglass reinforced nylon, a standard on all Spyderco knives. As mentioned earlier, the handle offers excellent grip, despite the size. Even when wet, there’s little chance it’s going to slip out of your hand and get lost somewhere.

The size, combined with the fiberglass reinforced nylon, makes this knife ultralight. Since the handle isn’t metal, you can carry the knife along with your keys with adding to the jingle in your pockets. The knife doesn’t come with a keychain, but can be attached to your existing keyring easily. There is no other tool included either.

Conclusion on the Spyderco Manbug: This is a quality keychain knife if you don’t mind spending $35. There’s everything here that you would ever desire from a tiny knife, and it performs beautifully.
