1. A nipper scissors usable by a person for cutting a fishing line, the nipper scissors comprising:
a first jaw including a first cutting edge and a first jaw pivot hub, the first cutting edge extending forward of the first jaw pivot hub, the first jaw pivot hub including first jaw keying structure;
a first lever including a first lever pivot hub and a first arm, the first arm extending rearward of the first lever pivot hub, the first lever pivot hub including first lever keying structure, the first lever keying structure being mated with the first jaw keying structure to form a first keyed connection between the first lever pivot hub and the first jaw pivot hub;
a second jaw including a second cutting edge and a second jaw pivot hub, the second cutting edge extending forward of the second jaw pivot hub, the second jaw pivot hub including second jaw keying structure;
a second lever including a second lever pivot hub and a second arm, the second arm extending rearward of the second lever pivot hub, the second lever pivot hub including second lever keying structure, the second lever keying structure being mated with the second jaw keying structure to form a second keyed connection between the second lever pivot hub and the second jaw pivot hub; and
a fastener pivotably connecting the first jaw hub to the second jaw hub and defining a pivot axis about which the first and second cutting edges are pivotable upward and downward with respect to each other for moving the cutting edges toward each other to a closed arrangement and away from each other to an open arrangement, the first and second cutting edges extending forward of the pivot axis, and the first and second arms extending rearward of the pivot axis;
wherein the first keyed connection connects the first cutting edge and the first arm for conjoint pivoting of the first cutting edge and the first arm about the pivot axis in which downward pivoting of the first arm causes upward pivoting of the first cutting edge, and the second keyed connection connects the second cutting edge and the second arm for conjoint pivoting of the second cutting edge with the second arm about the pivot axis in which upward pivoting of the second arm causes downward pivoting of the second cutting edge;
wherein the first and second cutting edges are biased by a spring away from each other toward the open arrangement;
wherein the first arm includes a first finger bed facing upward and the second arm includes a second finger bed facing downward, the first finger bed being configured to receive a first fingertip of the person, the second finger bed being configured to receive a second fingertip of the person, the first finger bed being arranged with respect to the second finger bed to permit the person to pinch the first and second finger beds toward each other between the first and second fingertips to move the cutting edges from the open arrangement to the closed arrangement;
wherein the first jaw keying structure comprises a first opening, and the first lever keying structure comprises a key received in the first opening;
wherein the fastener is in the first opening.
