9. The electrosurgical device of claim 1, wherein the one or more sliders are a first slider and a second slider.

10. The electrosurgical device of claim 9, wherein the first slider covers the first activation button, the second activation button, or both in one or more positions.

11. The electrosurgical device of claim 9, wherein the second slider is prevented from moving when the first slider is in the first position and permitted to move when the first slider is in the second position.

12. The electrosurgical device of claim 9, wherein the first slider, the second slider, or both are movable from the first position, to the second position, and a third position.

13. The electrosurgical device of claim 12, wherein the first slider when in the third position extends the distal end of the blade beyond the distal end of the first working arm and the distal end of the second working arm.

14. The electrosurgical device of claim 9, wherein a blade is movable with the first slider or the second slider.
