A device having one embodiment for severing a hypodermic needle at its hub and cannula with a single motion. The device has hub and cannula cutters that are joined at a slidable joint and pivoted at noncoaxial pivot points to provide increased mechanical advantage to the cannula cutter. In another preferred embodiment, the same type cutting mechanism has its cutters spaced so as to sever a hypodermic syringe barrel and a cannula of a needle attached to the syringe barrel in a single motion.
