 Many Orthodox Jews, especially Haredi Orthodox Jews, refrain from cutting their beards altogether, and, with the exception of occasionally trimming their mustaches with scissors when they interfere with eating, never cut their facial hair.Orthodox Jews who do shave their facial hair must utilize electric shavers, as opposed to razors.Some modern Jewish religious legislators in Orthodox Judaism, including Rabbi Moshe Feinstein and Rabbi Yosef Eliyahu Henkin, permit the use of electric razors for the purpose of remaining clean-shaven, because, in their view, electric razors work like scissors, cutting by trapping hair between the blades and a metal grating.
