Harry Brearley
Harry Brearley (18 February 1871 – 14 July 1948) was an English metallurgist, usually credited with the invention of "rustless steel" (later to be called "stainless steel" in the anglophone world).
Kitchen utensil
Stainless steel finds many applications in the manufacture of kitchen utensils. Stainless steel is considerably less likely to rust in contact with water or food products, and so reduces the effort required to maintain utensils in clean useful condition. Cutting tools made with stainless steel maintain a usable edge while not presenting the risk of rust found with iron or other types of steel.
