The Emerson Wave Shaped Feature®

By March 28, 2013January 4th, 2022Video

The Emerson Wave Shaped Feature ® is a registered trademark of Ernest and Mary Emerson. It is the design aspect that distinguishes an Emerson Knife.

The Emerson Wave Shaped Feature ® can be identified by the distinct wave shape located on the spine of the blade.

The Emerson “Wave Shaped Feature,” also called the remote pocket opener, is the most dynamic and advanced feature ever designed for folding knives. This device allows you to open the knife literally as it's removed from the pocket. This makes any Emerson knife with this feature the fastest deploying folding knife in the world. Faster than an automatic, your knife is open as it comes up into your hand, fully ready for use. Our “Wave Shaped Feature” is now officially required on all knives we supply to military combat units, military search and rescue units, and law enforcement agencies.



An important part of knowing the anatomy of an Emerson Knife is knowing how to utilize it. Using the  patented Emerson Wave Feature correctly, you can deploy the knife out of pocket rapidly. It takes some practice to master. See how it's done in the videos below.

    Would love to get one for my EDC1 (left handed please). Are they going to be available? Does anyone respond to these comments?

    Are you going to make anymore of these rapid deployment sheaths. Been waiting a number of years now.
