            As a kind of cutting tool, the necessary characteristics of the paper cutter is sharp and hard. In general, the sharp property can be achieved by fine grinding, while the hard property depends on the material itself. So, with this in mind, designers of paper cutters often choose some alloy steel as the main manufacturing material for paper cutters, rather than some iron which is cheaper and can reduce the cost.
