Assisted Opening Knives

Assisted Opening Knives

Assisted opening knives are pocket knives or folding knives that use an internal mechanism, similar to a switchblade knife, to open the blade with astounding speed. The difference in a switchblade, or automatic knife, and an assisted open knife is the blade must be opened to approximately 45° before the mechanism takes over and opens the blade. This is unlike a switchblade that only requires the press of a button to open the blade.

Assisted Opening Mechanisms

Different knife companies have different mechanisms and names associated with such. Some of the popular assisted open mechanisms include M.A.G.I.C. by Smith & Wesson, Outburst by CRKT, Tailwind Assisted-Open by United Cutlery and SpeedSafe by Kershaw.

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.
