## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to haircutting scissors and, more specifically, to a combination scissors and lighter for use when braiding synthetic hair. The present invention overcomes the difficulties encountered by someone that is adding braided synthetic hair extensions to another person. Once the synthetic hair is braided to the desired length it is then cut and the resulting loose strands are then burned to seal the end and prevent the fraying or unraveling of the braid. The hairdresser must hold the end of the braided section in one hand to keep the braid intact and then use the other hand to cut the ends of the braid with a scissor which then has to be put down in order to pick up a lighter to apply a flame to the loose ends in order to seal the braid. This method is not only awkward but time-consuming especially when a great number of braids must be cut and sealed. The present invention overcomes the shortcomings of the prior art by providing a scissor lighter combination that will give the hairdresser one tool with which to perform both the cutting and sealing of the braid. The present invention provides a combination scissor and lighter for the cutting and sealing of braided synthetic hair comprising a cutting implement having two blades joined by a swivel pins having handles at one distal end. One of the handles has a chamber therein for storing a quantity of a combustible substance therein. The chamber has an input valve for refilling the chamber and an output valve communicating with a conduit extending through the blade to the other distal end. Also located within the handle and extending therefrom is an igniter switch which when depressed opens the output valve on the chamber permitting the combustible substance to escape through the conduit to the distal end of the blade. Working in concert with the opening of the valve is means for sending an igniter spark to the end of the distal end of the blade whereby the combustible fluid is ignited.

An emergency escape tool is proposed for escaping from a car when an accident happens. Scissors for cutting a seat belt and a spike are provided. The spike is held at and retractably protrudes from a handle of the scissors. A tip of the spike is pressed against a window glass. A spike driver is housed in the handle. The spike driver usually urges the spike in the protruding direction. When the spike pressed against the window is displaced inwardly, the spike driver accumulates a compression force corresponding to the displacement. According to the accumulated compression force, the spike is promptly pressed toward the protruding direction so as to break the window glass.
