“The Chofetz Chaim when he referred to scissors was not discussing an issur l’halacha”
“Reb Elyashiv’s issur is based on the misunderstanding that the Likutei Halachos refers to an electric shaver.”
WADR, I’d rather go with Rav Elyashiv’s “misunderstanding”, than an unknown persons “understanding.”
“Reb Yaakov Kaminetzky is not true according to his son.”
It’s written in Emes L’Yaakov. Again, an unknown person’s asserted conversation with his son, against Reb Yaakov’s printed word.
