It seems like you're describing the features of a specific hair clipper or trimmer. The cutter head being quickly rinsable under running water is convenient for cleaning and removing any clippings after each use, which helps to maintain hygiene and prevent bacteria buildup. The quieter and more comfortable haircut process makes it suitable for use in barber shops as well as at home. The sharp t-blade you mentioned is designed to allow for precise cutting and outlining of various hairstyles, regardless of the direction you're cutting from. This makes it versatile and suitable for all types of hair. Additionally, the hair clipper or trimmer you're referring to has a fashionable appearance with a metal body and intricate carving patterns on the handle. This design feature adds to its aesthetic appeal, while the comfortable handle ensures ease of use during haircuts and beard trims. Please note that without a specific product name or brand, I can only provide general information based on the features you mentioned.
