Overview
BU 297 Sirus Special Edition assisted knife in Blue/Burgundy with skeletonized frame handle. Like other Buck assisted-opening knives, the Sirus has Buck's patent pending ASAP Technology - an advanced design that utilizes a dual pivot spring to provide constant force for a smooth, reliable, one-hand blade opening. The rolling cam lock safety and blade release ridge are integrated for convenient, one-hand ambidextrous operation.
Buck's ASAP Technology™ "assisted-opening" knives are functionally different from automatic knives (switchblade type) that typically use gravity or a handle button/lever to release the blade from a closed position. Buck's 2-stage operation (safety & blade release lever) is designed for user safety and does not use a handle button/lever. However, users are responsible for investigating laws applicable to assisted-opening knives in their jurisdiction.
