un-Helpful: I’ve already pointed out that most of your list of ossrim is a figment of your imagination. The Chazon Ish equated shavers with powder which is unanimously muttar, The Chofetz Chaim did not have electric shavers he assered the safety razor which is certainly a ta’ar, Reb Yaakov Kamintzky also never assered a shaver according to his son Reb Shmuel yblc. None of your other “sources” are any more then hearsay, which is not reliable.
However Reb Moshe Feinstein, Rav Shmuel Kaminetzky, Rav Heineman, Rav Tzvi Pesach Frank, and all Litvishe Rabbonim and Roshei Yeshivos have consistantly permitted shaving with an electric shaver.
