“SIRUS” B297-BKS

The Sirus spring assisted knife from Buck features ASAP Technology. Assisted opening knives, like the Sirus are functionally different from automatic knives that use gravity or a handle button/lever to release the blade from a closed position. Buck’s 2-stage operation, with safety & blade release lever, is designed for user safety and does not use a handle button. However, users are responsible for investigating laws applicable to assisted-opening knives in their jurisdiction.
