Investment/lost-wax casting with stainless steel.    

Heat treatment for increasing the hardness.

Investment casting (also known as lost-wax casting in the art world), is the  oldest known metal-forming technique.  The key benefits are versatility,  accuracy, repeatability, integrity, and the wax can be reused.  It is  more expensive than other casting methods; however, it can incorporate  intricate contours and the end components are near perfect, so they  require little or no rework once cast.
