5 The blanks are trimmed to the proper shape by cutting away excess metal. A hole is drilled through the blank. This hole will later allow two completed blades to be attached to each other.
6 The trimmed blanks are hardened by heating them, then cooling them quickly in cold air, water, oil, or another substance. The temperature to which they are heated and the medium in which they are cooled varies depending on the type of steel from which they are made and the desired characteristics of the blade.
7 The hardened blanks are heated again and allowed to cool slowly in air. This second heating, known as tempering, gives the blank a uniform hardness. If the blades of a pair of scissors did not have uniform hardness, the harder places on one blade would soon wear out the softer places on the other blade.
8 The repeated heating and cooling causes the blanks to warp. They are straightened by being placed on an anvil and lightly tapped with a hammer. This process is known as peening
