Quick, easy, one-hand deployment. An assisted-opening knife with patented ASAP Technology® and skeleton frame handle. A safety lock prevents the blade from accidentally opening, but after disengaging the safety the blade opens rapidly with the flick of your thumb. A pocket clip is included for easy carry. Made in the USA. Buck's ASAP assisted opening knives are functionally different than automatic/switchblade knives. Switchblade knives use a button/lever in the handle to release the blade and the blade cannot be moved at all without entirely opening the knife. As with many things, knife laws change and vary from location to location. It is the user's responsibility to comply with all regulations. For more information please visit www.AKTI.org.
