Abstract
Official abstract text for this publication.
A razor head includes a frame including two opposing long side walls and two opposing short side walls, connectors each connecting two points of the frame in an interior of the frame, and elongated blades arranged on an inner side of the frame. The blades are coupled to only two of the connectors, the two connectors to which the blades are coupled connecting the two long side walls to each other. In a case where a position in the frame in a longitudinal direction is represented by a percentage, when a middle of the frame in the longitudinal direction is 0% and two ends of the frame in the longitudinal direction that correspond to inner surfaces of the two short side walls are 100%, the two connectors to which the blades are coupled are each arranged in a range from 30% to 90% between the middle and the two ends.
