A method of manufacturing a blade for scissors includes steps of: fusing an alloy of zinc and aluminum; filling said alloy into a first mould for manufacturing a metal cutter for scissors; applying high temperature and high pressure to the first mould to form a unitary metal cutter; fitting the metal cutter into a second mould for manufacturing a blade; and squirting viscous resin into the second mould to partially enclose the metal cutter, whereby the blade is sharp, lightweight, durable in use and fit for mass production. |
