What is a swaged needle?

A swaged needle is a type of needle that has a precision-cut end rather than a sharpened one. It is made by cutting a small piece of metal tubing and smoothing and rounding one end. This type of needle is used for specialized procedures and typically requires a special holder or instrument to use. Swaged needles are often blunt or hollow and can be used for injections, aspirations, or biopsies.
