The blades of a metal cutter are shorter than that of blades of paper cutter scissor. give reason.

In order to cut the metals we need more energy and effort. If the effort distance is greater than load distance there will be magnification of force and the metals would easily could cut. So the blade of a metal cutter shorter than that of paper cutters.

metal are very hard. in other to cut metal we need more energy and effort. if the effort distance is greater than load distance there would be magnification of force and the metals could easily be cut
