Spring Assist Blade. Simply Push the Index Release!

Black Blade Green Micarta Handle.

Assisted opening knives are the hottest knives on the market. With a flip of the index release that sticks out of the back of the handle or the thumb stud on the blade, the blade is released using the spring inside. Because of the manual pressure applied and the lack of a push button to release the spring, assisted opening knives fall outside the federal definition of switchblade.
