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.

Technical Specifications

Frame Lock
A 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.
