Abstract: A disposable head adapted for one-time use as an attachment to an electric shaver for cutting hair of a patient close to the skin in preparation for surgery has a lower portion comprising a lower plastic member adapted for engagement with a portion of the body of a patient to be shaved and a lower thin metal blade insert-molded integrally with the lower plastic member at an upper region thereof and an upper portion comprising an upper plastic member and an upper thin metal blade insert-molded integrally with the upper plastic member at a lower region thereof. The blades are opposed to and in contact with each other when the head is assembled, and each of the blades has an edge formed with a row of cutting teeth. The rows are substantially parallel to each other, and the teeth of each row are relatively reciprocable with respect to the teeth of the other row so as to cut hair drawn between a tooth of one row and an adjacent tooth of the other row.
