" Cuticle nipper is a small tool that is used to trim or cut back the cuticles on the fingernails or toenails. These tools are usually made from a durable metal such as stainless steel. They are designed with a two-pronged handle that fits in the palm of the hand. At the end of the cuticle nipper is a metal jaw with sharp edges intended to grasp and cut away excessive skin around the cuticle. The jaw is usually one inch (about 2.5 cm) deep or less....
There is some debate as to whether or not it is good to cut the cuticles around the fingernails and toenails. Some people believe that cutting the cuticles is bad for the health of the nails. Other people believe that long cuticles look unkempt and unsightly and that cutting them back does no real harm. Luckily, there is a tool that does pretty much the same thing as a nipper without cutting away the cuticles.
For those who prefer not to cut the cuticles, a cuticle pusher may be used instead of a cuticle nipper. Instead of actually cutting back the cuticles, a pusher literally just moves the cuticle back and away from the nail. This leaves the nail bare and prepared for buffing or polish. A cuticle pusher is also more hygienic than a cuticle nipper because it is much less likely to cause bleeding around the beds of the fingernails or toenails."
