Convenient belt clip for easy carry and a safety lock prevents the blade from accidentally opening. 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.
