Quality starts with the material the quality of the steel has a crucial influence on the quality of the scissors or shears. It is fundamental for the efficiency and durability of the product. Steel alloys of the highest quality are the basic material for scissors and shears. Scissors used to cut cordite (an explosive substance resembling twine) must not produce sparks. Scissors used to cut magnetic tape must not interfere with magnetism.This quality steel provides the basis for exceptional cutting performance
Depending on the manufacturing process two different qualities of steel are used by manufacturers 
High-grade stainless for stamped household shears
Scissors and shears made of high-grade stainless steel 

The majority of scissors and shears by ABI Professional are made of high-grade stainless steel. Stainless steel is manufactured from iron, about 1% carbon, and at least 10% chromium. It is particularly recommended for scissors that come into contact with moisture because the steel will not rust in damp air. It has also the advantages of being light and rustproof
