Scissors are simple hand-operated cutting instruments, invented 3500 years ago in ancient Egypt. It is a simple mechanical tool, made by 2 blades, connected in such a way that the sharpened edges slide against each other.The idea is that I have an interesting lamp back there in Bulgaria and I think that the logic of scissors can be seen there. It is kind of improved mechanism, which allows the lamps arm to be pulled out and so the light can be directed much more easily.
