The Spyderco Sage3 knife is a collaboration with Blackie Collins, featuring a unique Bolt Action Lock mechanism. This lock is operated by a button on the side of the handle, connected to a steel bar that slides behind the blade's pivot. When you open the blade, the bolt moves, compressing a spring and locking the blade open by propelling it forward into a space between the blade and the frame. This mechanism is designed to provide maximum strength and lightness. The Sage 3 also boasts a flat ground S30V stainless steel blade and blue G-10 handle scales, along with a reversible wire pocket clip.
