6. The electrosurgical device of claim 5, wherein the forceps include a bias device that moves the shuttle from the second electrical configuration to the first electrical configuration so that the device can be switched from the second electrical configuration to the first electrical configuration or vice versa using only one hand.

7. The electrosurgical device of claim 5, wherein the first working arm and second working arm are both in direct contact with the blade electrode when the electrosurgical device is in the second electrical configuration so that the first working arm and the second working arm immobilize the blade.

8. An electrosurgical device comprising:
