Knife Country, USA

Assisted opening knives — often called spring-assisted knives — strike the perfect balance between manual folders and automatics. With a slight push on the thumb stud, flipper, or button, the blade deploys quickly and securely thanks to an internal torsion bar or spring mechanism. The result is fast, reliable action that makes these knives a favorite for EDC, tactical, hunting, and utility use.

Knife Country USA offers a wide range of assisted opening knives, organized by steel type, lock style, blade size, origin, and more, so you can find the right knife for your needs.
