1. A surgical tool, comprising:
an elongate shaft; and
an end effector operably coupled to a distal end of the elongate shaft and comprising:
a first jaw with a first axis of rotation, a second jaw with a second axis of rotation, the first axis of rotation and second axis of rotation are rotatable about an end effector axle;
a first blade that moves in tandem with the first jaw, the first blade having a third axis of rotation, a second blade that moves in tandem with the second jaw, the second blade having a fourth axis of rotation, the third axis of rotation and fourth axis of rotation are rotatably mounted to the end effector axel and laterally offset from the first and second axis of rotation,
wherein the first and second jaws are movable between a closed configuration, in which the first and second jaws are positioned adjacent one another, a first open configuration, in which the first and second jaws are separated and the first and second blades remain occluded, and a second open configuration, in which the first and second blades are exposed and a gap is defined therebetween.
