Nail scissors with a special ground tip are called combination scissors. They are used on fingernails but also for working on sensitive corners and cuticles. A good pair of scissors is distinguished by its smooth, regular cutting action, a distinct cut and the comfortable size of the rings. Scissors that are of especially high class quality also have a blade with a very fine micro-serration. Moreover high class manicure scissors are secured with a screw. This not only allows the blades to be precisely adjusted during assembly, but they can also easily be reground and adjusted if necessary.
