4 Most quality scissors are made from blanks formed by drop forging. Like cold stamping, this process involves shaping the blanks with a die. This die, known as a drop hammer, pounds into a bar of red-hot steel to form the blank. The pressure of the drop hammer also strengthens the steel.
Types of Steel Scissors Stainless steel is manufactured using iron, about 1% carbon, and at least 10% chromium. Stainless steel is lightweight and rustproof. Carbon steel is used to make scissors in which the handle and the blade form one piece. Carbon steel is manufactured using iron and about 1% carbon.
