This question already has an answer here:
While listening to a presentation being given by an orthodox Jew, he made a comment about shaving, and how he had to use an electric razor past a certain point on his face. It was just a conversational, in-passing remark during introductions for a meeting that had nothing to do with Judaism, so I didn't get a chance to ask about it. But I am curious...
I am not Jewish, but customs regarding hair are common in Christian and Muslim sects as well, so I totally get that part. This Wikipedia page and this SE question both do a good job of explaining where the custom comes from.
The distinction comes down to the use of a straight blade vs. a pair of scissors, but this argument doesn't make sense to me in our modern technological age.
If the religious objective is that you should not destroy the corners of the head and of the beard, how does an electric razor -- which accomplishes very nearly the same exact thing as a straight razor does -- be acceptable to that objective? It seems like splitting hairs to me (pun very much intended).
BTW, the guy giving the presentation was clean-shaven.
