Abstract
A hand tool (100) includes a head section (102) including a top jaw (106) and a bottom jaw (108), a handle section (104) including a top handle (112) and a bottom handle (114), and a joint assembly coupling the head section (102) to the handle section (104). The top jaw (106) is coupled to the bottom handle (114) by a first transition portion, and the bottom jaw (108) is operably coupled to the top handle (112) by a second transition portion. The first and second transition portions are pivotally coupled to each other by a pivot pin (140). The first transition portion is disposed on a first side of a longitudinal centerline of the hand tool (100), and at least a majority of the second transition portion is disposed on a second side of the longitudinal centerline such that a width of the first transition portion is less than a width of the second transition portion.
