SOG makes the only multi-tools in the world with one-handed flip opening and gear driven patented Compound Leverage for double the plier power the new PowerAssist takes these principles to a new level. This is the first multi-tool in the world that houses not just one but two assisted opening blades. Start to open the main blades, which are available when the tool is closed, and S.A.T. (SOG Assisted Technology) takes over to complete the opening. When not in use, blades lock closed using our patent pending side release. It never been easier! Flip open the tool and experience the precision of the heavy-duty plier capability and large wire cutters. Smooth handle surfaces promote comfort on even the toughest jobs. While open, four other components are now available and individually lock open with the new patent pending Piano-Locks. Youâ™re going to love playing these keys!
