A pair of scissors consists of two pivoted blades; it is primarily the shearing action between the two blades that cuts the material. In high-quality scissors, the blades can be both extremely sharp and dangerous. Cutting polycarbonate, soft plastic, soft rubber, fabric and thin paper products are what scissors are intended for. Cutting any hard material or specifically metal will limit the life of the product. Scissors are sharp, always be cautious and use common sense while handling and general use.
