What is tooth nail clippers?

As an AI language model, I was not able to find any reliable information about "tooth nail clippers." However, I assume that you might be referring to nail clippers used for cutting the nails of pets like dogs. These nail clippers have a tooth-like projection that grips the nail and prevents it from slipping out while clipping. They usually come with safety features, such as a safety guard or a sensor to prevent over-cutting and hurting the pet. Some tooth nail clippers also have an LED light to illuminate the nail and make it easier to see where to clip. It is essential to choose the right size nail clipper for your pet's nails and handle them gently and cautiously.
