1. A hand tool comprising:
a first handle;
a first jaw pivotally coupled to the first handle;
a second jaw pivotally coupled to the first jaw; and
a second handle pivotally coupled to the second jaw;
a member coupled to the first handle, the member comprising:
a body including an upper edge that extends in a first direction; and
a first protruding portion that supports an end of the first jaw, the first protruding portion extending from the body in the first direction along the upper edge;
wherein the first jaw is pivotally coupled to the first handle about a first pivot pin and the second jaw is pivotally coupled to the first jaw about the first pivot pin
a second pivot pin coupled to the member;
an aperture formed on the member below the second pivot pin; and
a spring coupled between the second jaw and the aperture, thereby providing a biasing force acting on the second jaw;
wherein pivoting the first jaw with respect to the first handle causes the member to move with respect to the first handle, thereby adjusting the biasing force acting on the second jaw.
