Assisted Opening Knives

Assisted opening knives merge function and speed to create a mechanism that opens a blade as fast and smooth as a switchblade. The difference between automatic knives and spring assisted knives is how the blade is deployed. An automatic knife deploys the blade on its own (no exterior finger force) with a trigger/button. A spring assisted knife needs an external force to engage the spring. Some states prohibit assisted opening knives so you'll need to check your state's knife regulations.

Assisted Opening Knives


We have the largest selection of assisted opening knives on the web! Each assisted knife opens with the speed of a switchblade, but is legal to carry in most states. We have out-the-front or side opening knives that are sure to impress! Check out our entire collection now, starting at only $6.99!

Top Customer Reviews - Assisted Opening Knives



  • Zach M. (Grayson, KY) - AWESOME!!!!!


    All I can say is wow this knife is amazing I bought it for my birthday and its so cool there is a lock on the side to keep it from accidentally opening in your pocket and the tip on this blade feels like a needle its pretty sharp at first but you can sharpen it more to make it really sharp the pocket clip also has an awesome design so I say you should buy it.


    Review of: Smith & Wesson OTF Assisted Opening Knife

  • Ted S. (Groesbeck, TX) - Best, Assisted Opening knife!


    Rating 5 star I have been searching for "The Knife" and I found it in this knife. It opens with such ease..I couldn't believe it. I have bought all kinds of knives and gave most of them away because they were not what I wanted. This is my knife. I give it 5 stars..super knife..great price.


    Review of: United Cutlery Rampage Assisted Opening Pocket Knife

  • Casey Tate (Reno, NV) - Wicked Fast Spring Assist!


    Great Knife ! Well made , good weight , very fast opening , just a little to long for every day carry. Would love to see a 9 inch model .


    Review of: United Cutlery Rampage Stiletto Assisted Open Black

  • Samantha Baker (Moultrie, GA) - Almost as fast as my automatic knives!


    Automatic knives and switchblades can get really expensive fast, so I decided to try out an assisted opening knife. The spring assist in this knife is super fast, probably as fast as some of my automatic knives! I've even talked a few of the other officers on the force into picking one up. I love it!


    Review of: Smith & Wesson M&P Assisted Opening Pocket Knife

  • Daryl Hall (Bainbridge, GA) - Great assisted opening knife for the price!


    I decided to try this knife because I wanted a CRKT Carson, but thought it was a bit expensive. This knife is the same size, CHEAPER and has a faster spring opening mechanism that the CRKT! The AUS-8 steel is really sharp out of the box and stays sharp pretty well for a cheap knife. I couldn't be happier! It feels like a $100 knife for under $20.
