Again R’ Kanievski I’m not questioning him, I’m just saying I have a minhag and mesorah that it isn’t assur to shave. I also have no connection to him that implores me to follow everything he paskens.
I know some of R’ Yackovs grandchildren and some of R’ Moshe’s grandchildren shaved. My father, grandfather and other choshuv members of my family, that live their lives c’halacha, shave(d) as well.
