Assisted Opening Knives Reviews 2024 & Buyer’s Guide

Assisted Opening Knives ReviewsThe assisted opening knife is one of a kind. It is by design a folding knife that opens up the blade by using an internal mechanism. Once the knife is half opened, it can further be opened up using a thumb stub which is attached to the handle’s side. Often this knife is mistaken for a switchblade knife.

Although, in these knives first the user has to open the knife about a quarter of the way before the knife itself opens up the rest of the way. The name of this knife is so because of some assistance required by the knife before it completely opens up. We have reviewed some of the Best Assisted Opening Knives for you.

How to Choose the Assisted Opening Knives

When choosing an assisted opening knife, there are several factors to consider to ensure you find the right one for your needs. Here are some important aspects to keep in mind:

Blade Quality

The foremost point to be kept in mind before choosing the perfect assisted opening knife for yourself is the blade quality. This is what determines the durability and life of the knife.

Locking Mechanism

The locking mechanism keeps the blade securely in place during use to prevent accidental closure. Popular options include liner locks, frame locks, and axis locks. Choose a reliable and sturdy locking mechanism that you feel comfortable using. The locking mechanism keeps the blade in its open state and prevents the blade from cutting into your fingers.

Knife Type

The edge of the blade needs to be decided before you buy your knife. There are three different options, either plain blade, fully serrated blade, or partially serrated combo blade.

Blade Length

The knife is available with a small blade that is lower than 2.75 inches in length, a medium blade that ranges from 2.75 inches to 4 inches, or a knife with a large blade that is more than 4 inches long. All of them have their own perks and disadvantages. It all depends on, as we said, the task you wish to perform.

Intended Use

Determine the primary purpose for which you’ll be using the knife. Are you planning to use it for everyday tasks, outdoor activities, self-defense, or a specific profession? This will help you narrow down the options and select a knife designed for your intended use.

Blade Material

The blade material affects the knife’s performance, durability, and maintenance requirements. Common blade materials include stainless steel, high-carbon steel, and various tool steels. Each has its own advantages and characteristics, such as corrosion resistance, edge retention, and ease of sharpening.

Blade Design

Consider the blade shape and edge style that suits your preferences and intended use. Different blade shapes, such as drop point, tanto, or clip point, offer distinct advantages for specific tasks. Additionally, choose between a plain edge or a partially serrated edge based on your cutting needs.

Handle Material and Ergonomics

Look for a handle material that provides a good grip and comfort during use. Common options include G-10, aluminum, titanium, and various types of synthetic materials. Consider the handle shape and texture to ensure it fits well in your hand and offers a secure grip.

Opening Mechanism

Assisted opening knives typically feature a spring-assisted mechanism that aids in quickly deploying the blade with one hand. Look for a reliable and smooth opening system, such as a thumb stud, flipper, or assisted opening thumb hole. Test the mechanism if possible to ensure it operates smoothly.

Legal Considerations

Make sure to familiarize yourself with the local laws regarding assisted opening knives. Different regions have varying restrictions on blade length, opening mechanisms, and carry methods. Ensure that the knife you choose complies with the applicable laws.’

Brand and Quality

Research reputable brands that are known for producing high-quality knives. Read reviews and gather feedback from other users to ensure the knife you choose is reliable, durable, and well-regarded in the market.


Set a budget range for your purchase. Assisted opening knives come in a wide price range, so determine how much you’re willing to spend. Remember that higher-quality materials and craftsmanship often come at a higher price.
