This is the highest-tooth-count wrench available: it has 160 teeth, giving it a click every 2.25 degrees of rotation. Two pawls, one on each side, each engage 12 teeth at a time with the outer ring. The direction knob in the middle determines which side of the pawls are in contact, and thus which direction the ratchet binds, and which direction it clicks. Unlike some high-tooth-count wrenches where the pawls engage alternately, one after the other, in this one both pawls engage every time, making the mechanism twice as strong.
