a sheath extending from the handle; and
a tool within the sheath and movable relative to the sheath;
wherein the handle includes:
an inner body;
an outer body disposed over the inner body, wherein the outer body is movable relative to the inner body;
a first actuator secured to the tool, wherein the first actuator has an actuated state permitting movement of the tool relative to the sheath in response to moving the outer body relative to the inner body;
a second actuator secured to the sheath, wherein the second actuator has an actuated state permitting movement of the sheath relative to the tool in response to moving the second actuator relative to the outer body; and
a first spring disposed between the first actuator and the outer body and within a cavity of the outer body, wherein the first spring is configured to (i) bias the first actuator radially outward relative to the outer body and (ii) bias the first actuator towards an unactuated state;
wherein the unactuated state of the first actuator and an unactuated state of the second actuator prevents movement of the tool relative to the sheath.
