The Buck Paradigm Shift Automatic knife is back, bringing the Shift Mechanism into play with a sleek upgrade for 2021. Originally a bolster lock, the 590 Paradigm now includes the automatic deployment option in the 591 model for rapid opening. Featuring CPM-S35VN stainless steel and G10 handles, this model combines advanced materials with a simple, yet effective design. The Shift Mechanism allows for smooth operation, making it perfect for those who appreciate innovative, everyday carry knives with a premium edge.
 
The Paradigm Shift deploys instantly by sliding the Cerakoted bolster lock up. It’s as easy as that—no complicated steps, just quick and reliable deployment every time. The gold fasteners make this knife stand out with premium aesthetics, while the G10 handle ensures a solid grip. This tactical piece also comes with a Cerakoted pocket clip for easy, legal carry and utilizes the same locking system for closure, simply sliding the bolster to lock the blade safely away.
