Abstract: An improved jumper cable organization is presented wherein illuminated indication is included to discourage improper connection of the improved jumper cable apparatus to associated batteries. A first embodiment of the invention includes a clamp securable to a jumper cable electrical conductive line wherein a spike is electrically associated with a plurality of LED units such that the spike electrically associated with an associated clamp may be contacted to a remaining terminal of a battery once the three remaining jumper cable clamps are secured to indicate appropriate polarity connection of the jumper cable organization. A second embodiment positions the plural LED elements within the handle of a battery connective clamp where an electrically isolated probe may be contacted to the remaining battery terminal for indication of appropriate polarity. The aforenoted LED elements with inappropriate connection of the jumper cables of the instant invention will illuminate to indicate an inappropriate polarity.

Abstract: A folding knife having a blade and a pair of folding handles. The handles are channel shaped and bifurcated at one end for receiving one end of the blade. The bifurcated ends of the handles are attached to the blades by adjacent pivot pins. Rotation of the handles to the closed position encloses the blade inside the opposing channels of the handles. The ends of the handles are coupled by meshing gears pivoted on the same pins so that the handles must rotate together in opposite directions through 180.degree. between closed and open positions.
