A lever device includes first and second levers coupled at a lever pivot. First end of a first bar is pivotally coupled to the first lever at a first lever-bar pivot. First end of a second bar is pivotally coupled to the second lever at a second lever-bar pivot. First tool is pivotally coupled to a distal end of the first lever at a first lever-tool pivot. Second end of the first tool is pivotally coupled to the second end of the second bar. Second tool is pivotally coupled to the second lever at a second lever-tool pivot and a second end of the lever is pivotally coupled to the second end of the second bar. First lever-bar pivot is between the lever pivot and a distal end of the first lever and the second lever-bar pivot is between the lever pivot and a distal end of the second lever.
