Abstract:  
Man, since the earliest times has endeavored to improve the material she uses for his daily needs. Through each period of history his armor, weapons, tools and vehicles constantly required improvements in order to protect himself and provide for his needs more effectively. The cold hammering of metal by the early armorer, metal craftsman and skilled blacksmith was an art. The shields, breast plates, spear heads, knives and swords were harder and stronger because of cold hammering. Today the process is no longer an art but a controlled mechanical process, originally called "Shot Blasting" by Zimmerli and later termed "Shot Peening" by Almen.
