Cast scissors are used to cut through a cast made of polycarbonate or light cast. The serrated scissors are very solid and exert enormous pressure on the material. For a stronger plaster cast, it is advisable to use plaster saws. There are hand saws or electric saws for this. You can also find individual saw blades in this category.
