Assisted Opening Folders

Assisted opening knives use a spring activated mechanism to deploy the blade when a little pressure is applied. Often confused with switchblades, they have one main difference. While automatic opening switchblades are usually opened with the push of a button, the assisted knife user must apply pressure to the blade, usually at the thumb stud, thumbdisc or index flipper. Once the blade is opened about 20%-30%, the mechanism automatically completes the opening.
