There’s no doubt that spring-assisted knives are all the rage right now. They’re popping up everywhere, and they’re incredibly handy tools for a good reason. But how do they work?
Indeed, we might be in the midst of a knife renaissance, with several options to choose from for blades. But one of the newer types of knives on the market, spring-assisted knives, is quickly gaining popularity.
In this article, we’ll explore how these knives work and some of their benefits.
What Are Spring-Assisted Knives?
The term “spring-assisted” refers to how the user opens the blade. The blade is opened manually in a standard pocket knife, either with your thumb or another finger. Since fixed blade knives don’t have a retractable blade, they don’t have a spring.
With a spring-assisted knife, a small spring located in the handle helps open the blade once you’ve initiated the opening motion. These knives need little to no effort from the user to deploy. They’re usually much faster, and some have complicated mechanics that enable the blade to release off the handle with a single button press.
The History of Spring-Assisted Knives
Spring usage to assist knife opening is a historical idea in 180that Henry Harper, an English chef, and author, promoted in his book “The Book of the Table.” Harper suggested using a coiled spring to help open a blade. However, no known knife from this period exists.
In 1980, the assisted-opening knife was patented by Michael Walker. This patent is for using a torsion bar (a metal bar that twists) to assist in opening the blade. It’s this technology that is still used in many assisted-opening knives today.
The first spring-assisted knives hit the market in the early 1990s. They were created by a company called Kershaw and based on the same era’s Japanese design. At the time, Kershaw’s knives were some of the only spring-assisted knives available.
The knives became popular with law enforcement and the military due to their speed and ease of use. They were so popular that Kershaw’s original patent ran out, and the market was flooded with cheap knock-offs. However, in 2005 Kershaw re-patented their design, and the knives once again became popular.
What Does A Spring-Assisted Knife Looks Like?
The vast majority of spring-assisted knives look very similar to one another. They typically have a dark handle with a light-colored blade. It makes it easy to see the opening mechanism when the knife is in your hand.
Most assisted knives have a thumb stud (a small protrusion on the blade that you use to open the knife) or a button to help open the blade. Some knives have a switch on the spine of the blade. This type of knife is typically larger and designed for more heavy-duty use.
Spring-Assisted Knives: Features and Qualities
Several features and qualities make spring-assisted knives unique, including:
The most crucial component is knives with blades that open with a bit of help from a spring. The assisted opening mechanism is located in the handle of the knife. So, when you apply pressure to the blade with your thumb or finger, the spring helps to open it—thus the name “spring assisted.”
Some knives also have a different locking mechanism that keeps the blade from accidentally closing. It is especially beneficial for people who are using the knife for self-defense.
Another vital feature of spring-assisted knives is the locking mechanism. It is a mechanism that locks the blade in place when it’s open, preventing it from accidentally closing and cutting you.
The locking mechanism is engaged when the blade is open and can be released by pressing a button or thumb stud on the handle.
Most knives also come with a pocket clip, which allows you to attach the knife to your pocket or belt for easy access. The pocket clip is usually located on the back of the knife, opposite the blade.
Some assisted knives also come with a belt clip, which attaches the knife to your belt so that it’s easier to access.
The vast majority of spring-assisted knives have thumb studs on the blade. It is a small protrusion that you use to open the knife. The thumb stud is located on the blade to open the knife with your thumb easily.
While most spring-assisted knives have blades designed for everyday use, there are also knives with heavy-duty blades. These blades are made for more intense tasks such as hunting or self-defense. The blades on these knives are typically thicker and more durable than the blades on standard assisted knives.
✅Strong grip handle
The handle on a spring-assisted knife is typically designed to provide a firm grip. It is essential because you’ll likely be using the knife with one hand, and you’ll want to make sure it doesn’t slip out of your hand. Handles with ergonomic grips are the most popular, as they provide a more comfortable grip.
How Do Spring-Assisted Knives Work?
It’s critical to understand the ins and outs of spring-assisted knives to prevent issues and dangers. As mentioned earlier, the spring-assisted opening mechanism is located in the knife’s handle. When you apply pressure to the blade with your thumb or finger, the spring helps to open it.
The assisted opening mechanism consists of the torsion bar and the cam. The torsion bar is a small metal bar located on the knife’s handle. It’s attached to the blade and helps open it when you apply pressure to it.
The cam is a small lever on the side of the handle that activates the torsion bar. When you press down on the cam, it causes the torsion bar to rotate and opens the blade.
The assisted opening mechanism separates a spring-assisted knife from a standard folding knife. A traditional folding knife doesn’t have a spring or any other mechanism to help open the blade, so you have to use your hand to open it. It can be difficult and time-consuming, especially if your hands are full.
Spring-assisted knives are so popular because they’re easy to open with one hand. You have to apply pressure to the blade, and the spring takes care of the rest.
Various Types of Spring-Assisted Knives

How to Sharpen Spring-Assisted Knives
Sharpening spring-assisted knives are pretty much the same as sharpening any pocket knife. The only difference is that you might have to be more careful when sharpening the serrated edge.
❗Prepare your materials.
For sharpening your knife, you’ll need a sharpening stone, honing rod, water, and a cloth.

This angle varies depending on the knife you’re sharpening and might vary from 15 to 30 degrees. It takes considerable practice to find the sharpening angle. However, you should be able to tell by the feeling. If you’re having trouble, you may contact the knifemaker and ask for assistance.

Once you have found the right angle, it’s time to start sharpening. You’ll want to use a circular motion when sharpening the blade. Apply pressure to the knife while doing this to ensure that the blade is sharpened evenly. Be sure to sharpen both sides of the blade.

After sharpening and honing your blade, wipe it off with a cloth. It will remove any excess material and help to keep your blade clean.
