Best Assisted Opening Knives in 2020

In a market that continues to well up with all kinds of assisted opening knives, we’ve made it our duty to only pick out the best assisted opening knives for you. Many people actually have difficulties distinguishing an assisted opening knife from a switchblade knife.

Unlike a switchblade knife, an assisted opening knife is the kind that utilizes an internal mechanism to complete the opening of the blade from its partially opened position. A thumb stump joined to one of the sides on the handle is what triggers the blade into the partially opened position.

Put simply, the user will have to apply some manual pressure to put the blade mechanism into an open, locked or ready-to-use position. Whereas there are those who actually relish the fact that you only need a button to get the knife in a ready-to-use position, there’s the other majority who prefer the extra effort it takes to have the knife in a ready-to-use position.

Assisted Opening Knife Buyers Guide

It’s easy to be overwhelmed by the many types of assisted knives available today and if you do, chances are high that you will make a wrong decision. However, we are determined to ensure this doesn’t happen. So read on to find out more about assisted knives.

Blade number

How many blades you wish the knife to have will depend on your personal preference or needs.  You have three options to choose from:

  • Single-blade knife
  • Multi-blade knife
  • Swiss army knife

Each of these options bears its own other special features. For instance, the single blade knife comes in multiple sizes and shapes and will be a great option for anyone looking to have an all-purpose knife. A multi-blade knife is an ideal option for those looking for various knife blades for different purposes. A Swiss army knife, on the other hand, bears a lot of other tools inside its handle and is also ideal for multiple uses.

Blade length

The blades come in different lengths. The categories include:

  • Small - under 2.75-inches
  • Medium – ranges from 2.75-4.0-inches
  • Large- over 4 inches

The kind of tasks you intend to use the blades for will influence the kind of length you will choose. For instance, light tasks only require a small blade length. Medium blades are perfect for any kind of task while the larger one works well for self-defence purposes.

Locking mechanisms

A locking mechanism is what helps to keep the blade open and in a position that won’t allow it to snap during use. An assisted knife can have any of the following locking mechanisms:

  • Liner lock
  • Slip Joint
  • Lockback
  • Mid lock
  • Frame lock
  • Ring lock
  • Lever lock

Liner lock mechanism: Manual pressure is used to get the liner back to its former position. To release the lock, the user will be required to relocate the liner to the side to pave way for the blade.

Slip joint mechanism: The slip joint mechanism utilises the tension from a flat or spring bar to hold the blade in place. Applying pressure on the blade triggers it to switch back to its closed position.

Lockback mechanism: This mechanism is a little old but still effective. It involves a locking arm that comes bearing a hook able to fit into a notch located on the blade’s back just behind the pivot. If you drag the hook, the knife will lock with a snap.

Mid lock mechanism: Currently one of the strongest locking mechanisms, it has its release mechanism right at the centre of the handle spine just close to the tip of the knife. Applying some pressure to the frame triggers the release mechanism.

Ring lock mechanism: It’s not only easy to use but also the cheapest and durable locking mechanism. It works by turning a ring wrapped around knife’s pipit to a position in which a break in this ring will let the blade to open. To close the blade, the ring has to be turned again.

Lever lock mechanism: A pin close to the pipit bolster helps to control the opening or closing of the blade.

Frame lock mechanism: Just like it is with mid lock mechanism, this release mechanism works when you apply pressure to the frame

Edge of a blade

When it comes to the edge of the blade, you also have different options to choose from:

Plain blade- perfect for skinning or shaving animals, performing cleaner cuts and pull cuts

Fully-serrated blade – Ideal for sawing and hard-cutting

Partially-serrate combo blade- a blend of plain blade and fully-serrated blade. Great for making push cuts as well as sawing


The cost of a knife will largely depend on the factors we’ve mentioned above, in addition to other factors such as the material used to make the handles and blades. Common materials include stainless steel, aluminium, Celluloid, Micarta, wood, Rubber, Kraton, just to name but a few. So all these factors will help you to narrow down on the knife that best suits your needs and this will certainly influence the pricing.

Another factor to consider is the carbon content. As much as it helps the blade to keep a great hold on an edge, it also puts it at risk of corrosion. So lower carbon content is recommended.  Not forgetting to mention durability (stainless steel is recommended), safety and comfort.

Once you have all these factors figured out, you will have an easier time finding an assisted opening knife that easily meets your needs. To get you started, we’ll list the most reliable assisted opening knives to have in 2020.
