The QuickFire is an assisted-opening knife with ASAP Technology. The QuickFire has an advance design with dual springs to provide an easy and safe blade release. The "quick-firing" blade has a convenient one-hand ambidextrous deployment. The strong mid-lock design and rotating blade safety provide a durable locking strength in the open or closed blade position. Equipped with a reliable 420HC blade steel and stylish steel reinforced handles, this knife is dependable and contemporary in design. 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 visit www.AKTI.org.
