[toc]A switchblade is a term used to define a knife with a foldable blade. In most cases, the blade can be folded sideways. There are several types, including manual, automatic and assisted. As such, automatic knives are a type of switchblades.

Keep in mind that automatic knives are not the same as assisted knives. They can be opened with a press of a button or a lever, while assisted require the use of your thumb. The difference is in the automatic system that opens the knife.

If we take a look at the legality of automatic knives we can see that the same rules as for switchblades are used. This means that an automatic knife is legal in most states and countries and it is considered as a pocket knife, used to open mail, packages and etc.

How to Choose the Best Automatic Knife in 2019

Best Automatic KnifeSource:GogDog

When looking for the right automatic knife, some factors must be considered first. Now, we will reveal those factors and we will guide you through the process of choosing a knife of this kind that is just right for you.

Release mechanism

The first thing to consider is actually release mechanism. It is a system used to unfold and fold your new knife. There are several differences of types available on the market. They are:

  • Secret mechanism- It is precisely as the name suggests. It has a hidden lever or a button and only you will know how to open your knife.
  • AXIS Pull- This mechanism is rare, very rare if we may add. It means that the buttons for the release are present on both sides.
  • Lever- It is as simple as it sounds. A knife with a lever mounted on one side.
  • Button- An alternative to the lever style. The operation is the same.


As you would expect, the best automatic knife must be made from proper steel. There are no ceramic, iron or any other material in this case scenario and honestly none of them will work well as steel.

There are specific types of steel we recommend. They are D2, Damascus, CPM S30V, 4034 Black, 400 Series, and AUS8. If your new knife is made from these materials it will last longer, be extremely strong and easy to maintain.

The bottom line here is that a knife must be easy to sharpen, yet strong and reliable. The blade must be immune to corrosion and stains while maintaining its sharpness as long as possible.

Blade length

Sadly, we cannot generalize this factor. It is purely your, individual preference. Automatic knives come with blades of all sizes. They start at 2 inches and may reach 10 inches. Smaller knives are more compact and more affordable, yet unable to meet more advanced usages.


Handle can be either made from plastics, wood or aluminum. Steel is also possible but usually avoided due to the extra weight it adds. Plastics is the worst option and reserved for the cheapest knives. Wood is elegant, durable, yet not as strong as the next alternative. Aluminum is the best and the strongest handle material. In addition, reinforced fiberglass is a valuable alternative.

Clip or holder

Where you are going to place and how you will carry your new best automatic knife? You have two options. The first is a clip which allows you to place the knife to a belt. It is more affordable, smaller and for some more desirable option.

A second option is to get a pouch, a case or a holder. It is a more elegant option and it is rare, simply due to the fact automatic knives are foldable and people usually find holders complicated and annoying.

Safety lock

It is definitely one of the most important features. A safety lock will make sure your knife can’t be opened accidentally. Sadly, not all models come with it and it is relatively difficult to find one which offers it.

If you are new in this realm, we recommend you to get a unit with the safety lock. It is still easy to use, yet it is 100% safer and even looks better. The locking mechanism makes the knife look more expensive.


If you are planning to carry your knife with you at all times, you need a lightweight model. In general, units with a weigh of 3 ounces are considered the most appealing. Models with a weight of 5 ounces are slightly bigger yet worthy of your consideration. Anything above 10 ounces and you have a big, impractical knife.


For us, the Smith & Wesson SWMP4LBS 8.6in High Carbon is the favorite automatic knife due to several advantages and it’s price point. It is made from 4034 Black Oxide steel, has an aluminum handle, locking mechanism and all of this comes at a low price. As such, we give it 4.9 out of 5 stars which is the best possible score. Take a closer look at other models from the list. They are also worthy of your attention.
