Why Buy An Assisted Opening Knife?

One of the first things to ask yourself is “why do I want to invest on a assisted opening knife?”. This is the most important question to ask throughout the purchasing process. If you’re going to buy a knife for show, an assisted opening knife is not for you. A heavy utility knife will do if you want to focus on appearance rather than function.

If you’re looking for a knife for self-defense or something you can use everyday, an assisted opening knife is the perfect option. It can take abuse and still be durable, you can use it for carpentry, cutting thin wires or steel, etc.


Depending on how many times you will use it, durability is a major factor in knowing a knife’s worth. Usually, knife owners will complain about knives that are subpar and don’t deliver in durability.

You can check for a particular knife’s durability by reading forums about a particular brand, talking to other knife aficionados and asking questions like “what materials were used in making this blade?” and “can it cut through steel?”


With most pocket knives, you may get knives with one of many different edges, all of which have different uses and all have their ups and downs.

  • Plain edge: A plain edge is great for smooth cuts and slicing. This kind of edge is ideal for self-defense and all-purpose knives where you do not want the knife to grab ahold of anything. Rather, you want it to slide with ease.
  • Combo edge: Some say that the combo edge is the best of both worlds, but ironically, it seems like the worst of both worlds too. What I mean by that is, it gives you the opportunity of using a serrated edge or plain edge depending on your needs. It’s a perfect all-around knife, but like a jack-of-all-trades, it is master of none.
  • Serrated edge: A serrated edge is perfect for sawing through objects when it needs to shred and grip. Ropes and branches are examples of things a serrated blade can slice through. However, if you’re looking for a blade for self-defense, a combo edge or even a plain edge would be better suited.


Usually, an average assisted opening knife is around 3 to 4 inches. It’s small enough to hold in the palm of your hands and carry around, heavy duty enough to endure abuse through time, and light enough to easily open.

An assisted open knife is fast to use, even faster for someone who’s experienced using it. It can be opened automatically yet are legal to a wide range market. This is the main reason it is favored by most because it does the job while remaining accessible, compact, and legal.

Blade Shape

Another thing to consider when buying an assisted opening knife is the shape of the blade. Many assisted opening knives are functional and work for many purposes, while others are designed differently. Here some of the many types of blade shapes of assisted opening knives.

Drop point

One of the most common blade shape types is the drop point because of the excellent all-purpose blade. The dull end (spine) of the knife is dropped down to the tip in a slight curve.

It’s a perfect hunting knife because you can control the point of the knife and large cutting edge.

Clip point

Another blade shape type is the clip point. The dull side is forged straight from the handle until about halfway, where it’s shaped into a curve like crescent, or straight to the point.

A clip point blade shape is ideal for piercing. The cutting area is large enough for slicing too.

Spear point

A spear point blade shape is forged where the point is in line with the long axis of the blade and has symmetrical edges. It can be double edged ( both are sharp) or single edge. A spear point blade shape has a sharp and strong point, but not ideal for slicing.

Type Of Steel You should Look For

When buying an assisted opening knife, one consideration is the type of steel blade it’s made from. When looking for the type of steel, you encounter these things: sharpening ability, edge-retention, and corrosion-resistance.

Unfortunately, like everything in life, nothing is perfect. You can’t purchase a perfect blade with all features. You might need to settle for one feature more than the other.

For example, an S30V steel has the best edge retention, but it’s very difficult to sharpen.

Types Of Blade Release Instrument

Back in the old days, you would need to open a knife by using both hands. Usually, you need to dig your thumbnail into the nick near the spine of the knife, then you can pull the blade out.

You may find these kinds of knives, but now, assisted opening knives can be opened with one hand.

Most assisted opening knives can be opened with one hand. Each assisted opening knife model may have its unique mechanism, but there are three basic mechanisms to date:

Thumb Stud

The thumb stud is the most common release instrument out there. It is located on the side of the blade and can be on one hand or both.

A thumb stud that’s located on the side (dual thumb stud) allows you to open from either side, so it’s perfect for people who are ambidextrous. To use it, put your thumb on the thud and extend it to swing the blade out.

Am assisted opening knife that has a thumb stud release is very easy to use because it gives your thumb a good grip on the blade and prevents accidents.

If you’re going to buy a thumb stud knife, you should consider the size and whether you want a one-sided or dual one.

There is another variation of a thumb stud called a thumb disc. It’s like a stud -- expect that it’s positioned flat on the spine of the blade, while a stud is located on the side. The disc makes a protrude motion on both sides which makes it ideal for ambidextrous people.

Thumb Hole

A thumb hole is located on the blade itself that’s usually round in shape, so the thumb can maneuver the blade in and out. The advantage of owning a thumb hole assisted opening knife is that it is ambidextrous. It provides an easy opening mechanism without any extra material like a thumb stud.

In my opinion, it’s probably the easiest to open with your hands, but some say it can be difficult when you’re wearing gloves.

Here is a video about knife opening methods:


A thud and hole knife calls for the thumb. On the other hand, a flipper uses the index finger. The flipper is usually located on the spine of the blade, and it’s usually ambidextrous. It provides a safety feature between your fingers and the blade because of the distance between it.

The flippers also acts a finger guard while you’re using it. I suggest choosing a flipper mechanism if you’re more comfortable using your index finger.
