International ClassB26B 013/00Foreign Application Priority Data1996-06-28 DEAbstractA pair of electrically heatable scissors includes two pivotally connected limbs and a current supply. Each of the limbs has a handle region and a cutting region. A blade of at least one of the limbs is formed from an electrically heatable layer or insert that is electrically connected to the current supply. Alternatively, the limbs may be formed in the cutting zone of a single material that can be locally electrically heated when supplied with an electrical current. Scissors of this type are simpler and more effective than scissors that have limbs heated by electrical resistors.Other References
