Dr.dre talking about scissors

Hi!  I'll be telling you about scissors today.  Some of the parts are wedge, lever, gear and something else.  It was invented by Romans around ad 100.  Scissors can also be ysed for cutting various thin materials such as paper, cardboard, metal foil, thin plastic, cloth, rope and wire.  Scissors can also be used to cut hair and food.  They consist of a pair of metal blades pivoted so that the sharpened edges slide against each other when handles (bows) opposite to the pivot are closed.  That's all i've got so bye!
