The grooming tool represented by Guillotine Nail Trimmers is indeed named after its design and function. Guillotine Nail Trimmers work by using a sharp blade that moves through a circular opening, resembling a guillotine, which effectively trims the nail. This tool is particularly useful for a clean cut and is favored by many groomers due to its precision and ease of use.

The other tools mentioned serve different purposes in grooming. A dematting rake is designed for removing mats and tangles from the fur, while nail scissors are similar to Guillotine Nail Trimmers but operate differently and may not provide the same level of precision for larger or thicker nails. Nail grinders use a rotating tool to file down the nail rather than cutting, making them a different category of nail care device. Hence, "Guillotine Nail Trimmers" accurately describes the tool in question.
