What Should You Consider When Choosing An Automatic Knife?

1. Size

When choosing a foldable automatic knife, you have to consider the size, especially after considering where you're going to put it.

In addition, you should also realize that in some parts of the world, carrying a big automatic knife is prohibited.

Therefore, you should go through the laws within your state or country to see what sizes of automatic knives are allowed.

This will save you the headache of getting arrested and also allow you to use your foldable knives in peace.

If automatic knives of all sizes are legal in your state, then the only other thing you should think about is where you'll be carrying your pocket knife; this will give you a good idea of the size to work with.

You should also consider the size of your hand as you're picking your knife for everyday carry. Automatic folding knives that are smaller in size are great for precise tasks, while bigger ones are great for hard tasks.

2. Construction

The construction of pocket knives affects their performance. Therefore, as you choose the one you want, consider what kinds of tasks you'll be doing with it.

Why is construction important? Because good construction ensures that your knives will not break down after a few uses. If high-quality materials are used, and the parts are properly assembled, you will have a knife that lasts for a long time.

Therefore, whether you want to get Kershaw Link pocket knives or any other knives on our list, ensure that they are durable. This will also give you peace of mind as you use your knife because you know that it can handle a lot.

If you don't intend to use your knives for hard tasks, you may enjoy ones with softer stainless steel blades. In addition, these stainless steel blades are easy to sharpen, which can give you an easier time.

3. Folding Vs. OTF

Although most of the knives we've looked at today are foldable knives, there's also another option. This is the OTF (Out-the-Front). Here's another factor that reminds you to check your rules to see if automatic knives are allowed in your state.

Anyway, once you've confirmed that you have the green light, you can consider if you want an OTF knife or a foldable knife.

4. Style

There are several styles to consider as you choose your knife. Some of the various styles include tactical automatic knives, everyday carry knives, and lots more.

Tactical knives are durable, fast, and precise. This means that if you intend to use your knife in high-stress situations, consider a tactical knife. Our first two picks are great examples of this.

Everyday carry knives are similar to tactical knives but have more finesse and flash. Whether you choose a tactical knife or an everyday one, ensure that it fits your preferences and style.

You can also consider if your tactical knife comes with a glass breaker if that's something that you want.

5. Use

Knowing what you'll use your durable knife for will allow you to choose the right features. Whether you want assisted opening, a reliable liner lock, a glass break feature, a reversible pocket clip, or even an additional safety lock, knowing what you need beforehand can help with the selection of a good automatic knife.

Frequently Asked Questions About Automatic Knives

1. What is the liner lock mechanism?

The liner lock mechanism is found in folding pocket knives. In addition, it is often found in knives that are for use with one hand. This liner lock mechanism allows you to close and open your knife with one hand.

Although they are convenient, liner lock knives are not the best when you're working on heavy tasks. This is because these liner lock knives are made from thinner pieces of metal and can wear if exposed to hard tasks.

2. What is an assisted folding knife?

An assisted folding knife is a knife in the folding knife category. This assisted folding knife uses an internal mechanism to open once you've partially opened it.

You can use a flipper or thumbnail attached to the blade to partially open it before the internal opening mechanism takes over.

3. Is glass-reinforced nylon good for knife handles?

Yes. Glass-reinforced nylon is a good material to use when making knife handles because it is stable at high temperatures, strong, impact-resistant, and has good chemical inertness.

Therefore, if you find a knife that has glass-reinforced nylon for its handle, you know you're in good hands.

4. What is a serrated clip point blade used for?

Using a back and forth motion, you can use this clip point blade like a small saw. With this feature, you can cut through ropes, belts, and even fabric if you have a razor-sharp blade.

Any other substance that's flexible and soft can also accommodate serrated blades. The advantage of a serrated option is that it can do some things that a drop point blade cannot.

5. Is an automatic knife worth it?

Yes. These knives make amazing self-defense weapons and are easily portable. This means that you can seamlessly use them anywhere and everywhere without worrying about hurting yourself or others when carrying them.

Another thing is that these knives are very handy, especially when you need to do tasks that require you to use one hand. Not many knives can handle this. Once you get the perfect tactical knife that matches your needs, you may never go back.
