The present disclosure relates to a razor which is easy to wash and includes a through-hole connected to a cartridge via a handle, the razor including a razor blade cartridge including at least one razor blade, and a handle coupled to a rear surface of the razor blade cartridge, wherein a through-hole which extends along at least a portion of a profile of the handle is formed on the handle, and the through-hole includes a first open surface formed to face the rear surface of the razor blade cartridge and a second open surface which is opposite the first open surface such that, since washing water is supplied through the through-hole which extends along a portion of the profile of the handle, washing of the razor blade cartridge can be facilitated, and by providing an open surface which is more perforated downward, discharge of washing water and shaving debris can be facilitated.
