Abstract: Nail clippers are provided, which reduce the striking velocity of the lower plate blade and upper plate blade when using the nail clippers and remove the noise effectively. Nail clippers comprise: an upper plate in which the first blade is formed in one side and the handle part in which a user gives pressure is formed; a lower plate in which the blade is formed in order to correspond to the first blade and the handle part in which a user gives pressure is formed; a fixing unit which connects in order to pivot the upper plate and lower plate; and the buffer material for relieving the noise which appears when cutting fingernail using the nail clippers. The buffer material uses the rubber.
