Hypodermic needles are normally made from a stainless-steel or Niobium tube [17] through a process known as tube drawing where the tube is drawn through progressively smaller dies to make the needle. The end of the needle is bevelled to create a sharp pointed tip, letting the needle easily penetrate the skin. [18] A hypodermic needle tip under ...
