Buying Guide for the Best Auto Knife

Do you want to buy a worthy product and get a good deal of the best automatic knives under $50? Then you need to sit with the information and do a little research about the essential facts of the cheapest switchblade.

So, let’s have a look at the following points.

Types of Automatic Knives

Knives have been used for our day to life for centuries, and to meet up our demands, they have branched out into different styles and shapes. These variations make a hassle to pick the right model for any task.

The type of auto knives depends on how their blade deploys. According to these criteria, the best switchblades/ automatic knives are of two kinds.

Out- the- front ( OTF)

OTF knives are switchblade types of knives. This automatic knife can deploy the blade ‘automatically’ by pressing a button or switch. Here the edge simply comes ‘out the front.’ That’s why it is called OTF knives.

They are a narrow slice of the market. Users prefer to OTF due to its double action like the knife can retract and eject at the same time.

Out-of the- side (OTS)

As the name indicates, OTS is one of the automatic blades where the blades deploy outside its handle. The OTS is flexible for utility use while OTF is for personal protection.

You will be glad to know that, according to recent statistics, OTS is the best flipper knives under $50

Knife law

Everyone likes automation, and somehow every teenager cherishes a dream to keep a foldable knife to them.

But it is not an easy task to store knives unnecessarily because this option is unsafe and can be dangerous for anyone. So, carrying knives is forbidden in many regions of the world.

There are separate knife laws in developed countries like the USA, UK, Australia, Sweden, Spain, Russia, China, Canada, Belgium, etc. According to their legislation, it’s illegal to buy, import, carry, or process weapons( knife)disguised as other objects.

But it is excellent to use knives for professional purposes such as chefs, hunting, pocket knives. Still, you have to ensure the authority that you won’t join in any offensive work with the blades. If you do so, then it will be punishable.

Knife Mechanisms

An automatic knife is also known as a pocket knife, portable knife, folded knife, etc. These kinds of knives consist of a sliding blade. There is a spring connected with the sword.

Most of the time, switchblade designs incorporate a locking blade. The blade can manually unlock by operating a mechanism. It also allows the edge to be folded and closed.

The position of the blade is attached to a spring. It controls the movement, and it creates a state which will be in the 1st position.

The two springs fit into the blade slide, and this amalgamation creates a resting phase. Then another holder offers a flat place to fix at the blade’s edge—the mainspring balances with the other holder’s side to the previously set aside.

At that moment, the central part begins forcing the edge, and then the carriers get enough space to move. It creates an adjustable pressure on the side and locks the right carrier. At this stage, a ramp on the slide sticks to the lower pin.

When the pin finds a safe place, then the blade and right spring holder are free to move. The exact holder can circulate within a fixed area.

Then the primary blade holds another edge for further actions. It pushes the edge of the knife and eliminates the need to strengthen your grip before opening it.

Blade material

The quality and durability of the knife depend on its blade. A high-carbon steel blade offers you excellent hardness. It holds the sharpness for a more extended period, but at the same time, this type of knife tends to get discolored.

On the other hand, stainless steel blades have extreme hardness and provide exceptional durability.

So, titanium blades are the best options according to their service. They are lightweight, durable, and provide better sharpness.

But the matter of regret is that they have a shorter life span because the various sharpening process erodes the metal.

Blade types

A saying goes, “There’s more than one way to skin a cat. This idea may be found in the aspect of knives as well. There are about 12-20 kinds of knife blades. Those are vaguely popular with pocket knives. Different knife blades are of different shapes. Such as

Clip point:

Clip point, a familiar blade shape, is characterized by a front section spine that seems to clip off. The clip point’s cut-out area may be straight or concave, and it is ideal for the precision task.

Drop point:

The drop point has a curved spine that curves down from the handle to the end. This one is best for general purposes and hunting because this knife has an easily controlled point and a bigger belly for slicing.

Gut Hook:

This one is more than a blade shape; there are more features to it. The gut hook appears with a smaller look with a sharp hook. Hunters choose it as the best option.


Talons have a spine and edge that curve down in the same direction to create a downward-facing shape. This blade efficiently cuts when you pull them back during the handle.

Most of the users utilize it for practical tasks such as cutting carpet, linoleum and pruning vegetation.

Straight Back Blade:

This is a regular blade with a straight back. It has an edge that curves up to meet at the tip. This option is sturdy and heavy for chopping or slicing.

A new user of the blade has to put pressure on the blunt area. A straight-back blade is one of the best auto-folding knife options to choose from.


This is quite similar to the previous one. AS the name indicates, this blade was suitable to trim the hooves of the ship, but nowadays, we are using it as a rescue tool.

Spey Point:

Spey Point is a flat edge blade design. This knife closes to the point when it curves to the tip. Spey has a short belly and broad tip, and this prevents accidental piercing.

For hunters, Spey is one of the best choices because this is one of the best knives that you can find available.

Knife Handles

Knife handles play a ‘comfort zone’ part in selecting any knife. You won’t pay a single penny to them, which are unmanageable or difficult to handle. In the same way, knife handles should provide a firm grip while performing heavy tasks.

Once upon a time, a bone was familiar material for knife handles. Nowadays, manufacturers are using carbon fiber, aluminum, titanium, stainless steel, and fiberglass also.

You will be surprised to know that many companies use synthetic materials like Micarta and G-10 as the base of knife handles. These materials lengthen the durability of the product, balancing with style and functionalities.

These are the basic facts you need to know before buying the perfect automatic knife under $50. You are maybe wondering with all these facts. But these are vital to know for shopping within your budget.
