ABSTRACT:
A Capo comprised of two hingedly connected jaws with a torsion spring which urges the jaws toward a closed position, and a hand operated toggle type of linkage operating against said spring to open the Capo. The force needed to be applied to the toggle linkage drops as the Capo is moved toward the open position reducing the effort required to maintain the Capo open while moving it to a new position.
