11 Best Assisted Opening Knives

Knife is undoubtedly the most versatile EDC piece of gear. Leave alone keeping you ready for the next apocalypse, a decent blade by your side will help a great deal in your daily endeavors, no matter what the day may bring forth.

Of course, for a tool that you’re going to need to use often, you need to get the one with the best features. Most knife experts will tell you to pay heed to the construction type, design, portability, ergonomics, size, and shape.

Sure, the above are the main features one has to consider when shopping for a knife. However,  we have a few seemingly minor things most people more often overlook. Surprisingly, these aspects can make a huge difference, especially on user convenience. A case in point is the blade deployment mechanism.

Your knife’s deployment mechanism will directly affect the speed of blade access, something that could make you live to see another day the next time you are in a live-or-die situation. That’s why if you are intelligent enough, you are going to pay heed to the seemingly less critical things about your knife when shopping for one!

For faster blade access, assisted opening knives work perfectly. The knives require the user to initiate the deployment process. It can be through the thumb stud or flipper index tab. After reaching a certain point manually, the spring assist mechanism comes in and makes the blade open fully.

Now, whether or not conversant with assisted opening knives, picking one option from the plethora of models can be a real puzzle. But not any longer— our article will be taking you through some of the industry’s finest assisted opening knives. Here we go!

Frequently Asked Questions

What are Assisted Opening Knives?

They are also called spring-assisted knives and use springs to help in blade withdrawal. However, the user has to initiate the opening with a flipper/thumb stud on the handle.

What’s the difference between assisted opening knives and automatic knives?

Although there’s an aspect of automation in assisted opening knives, they aren’t the same as automatic knives. For the A/O, the user opens the blade to about one-quarter of the way before the mechanism does the rest. Automatic knives work with a mere push of a button.

Folding or open assisted – which is the best knife?

While they are all great, assisted opening knives offer more convenient features than folding options. For instance, with the spring-assisted opening knives, you can open the blade with one hand. That’s a handy feature you can’t achieve with a typical folding knife.

Where’s the best place to buy an open assisted knife?

Definitely, it has to be online. Online shopping will allow you to compare the price of different knives relative to the features they offer. It also provides an opportunity to know how a product performs through reading customer reviews of people who already have experience with the product. Now, we recommend that you do your shopping on Amazon. This site offers the best prices and fast shipping, especially for a prime member.

Are assisted open knives legal?

Since they aren’t automatic blades, they are legal in most countries. However, the tool must rely on one hand or thumb for opening. It should also have a mechanism for safety.
