I have been reading from a sefer called Hadras Ponim-Zokon (link online-https://koshershaver.info/) stating that it is completely asur gamur to shave, possibly even with scissors. The Targum Yonason, who was a tanna, forbids even scissors, because of Lo Silbash
I myself am still a bachur and never shaved M'Safek, but I read in Orchos YosherOrchos Yosher, which R' Chaim Kanievsky ruled in his perek on shaving, that scissors is asur. And he brings a story from the Gemora (Berachot 11a) that two tannaim, Rabbi Yishmael and Rabbi Elazarben Azarya, were davening maariv, and one stood up for Shma, to show that the Halacha follows Beis Hillel. The other Tanna said to him- You are like one who has a full beard, and people ask- why don't you cut your beard? and he says because some people use a razor, and are oiver on a D'Oiraisa.
Here is an image from the sefer where Rav Chaim said this:
My question is about this proof. Shouldn't this gemara prove the opposite, that scissors are mutar, because he said that some use a razor and are oiver, butwith the implication that other than a razor is mutar?
