The safe way to practice your wave shaped opening feature skills
The Emerson "wave shaped opening feature" is a fast, effective, and impressive way to open your knife.
The patented Emerson "wave shaped feature," a small wave-shaped tab on the top of the blade that's built to catch on your pocket seam, opens the knife as you withdraw it from your pocket. This instant-open feature is a favorite among military, rescue, and law enforcement knife users.
But it does take a little practice.
Enter the Kershaw-Emerson E-Train, our Emerson trainer knife. The blade is unsharpened so you can safely practice using the wave shaped opening feature without endangering either your pocket or your fingers.
The E-Train's G-10 front scale is in safe-training blue for easy identification. There's a left/right reversible pocketclip so you can easily carry it with you to train whenever you have a spare moment.
Frame LockA portion of the handle (the knife frame) moves behind the blade to lock it into position during use. This is a safety feature of the knife. Reversible Pre-drilled holes in the handle enable the user to change either the tip position or the side on which the knife carries.
