Abstract: A weighing device includes a tubular housing, a pair of levers pivotally secured the tubular housing and each having a jaw biased to grasp an object to be weighed and a handle for moving the jaws away from each other against a spring. The jaws are movable away from each other to grasp the object when the handles are moved toward each other, such that the handles may actuate the jaws away from each other to grasp the object. Two links have outer ends secured to the levers and inner ends secured together. The spring may bias the links to force the handles away from each other.
