Question

Peace and blessings.
I wanted to ask the Rabbi his opinion about using electric shavers—whether they are considered a razor or not. I saw that the Rabbi was asked about this in the past, but there the main issue was the nature of the cut: whether it is done like a razor or like scissors.
I wanted to ask for another reason: is it simply a rabbinic view that something classified as a razor is permitted even when the result is equivalent to an actual razor, or is it forbidden by Torah law?
I saw that the Hazon Ish forbids it on the basis of Torah law. And it seems to me that one has to say honestly that his words are very clear, and just as in the parable of the “swimsuit” that the Rabbi often speaks about, it becomes clear that one must follow the substance and not an arbitrary form, so here too the Sages certainly did not create a leniency on an arbitrary formal basis, but rather in a substantive way.
And although it seems to me that one could posit “hidden variables” that would explain why this particular form of cutting is prohibited according to some “hidden variables” underlying the prohibition, it is doubtful whether that is really possible. And according to the reasons that appear in Sefer HaMitzvot, this is a commandment whose rationale depends on the result of the prohibition—that is, on the actual appearance it creates.
In addition, on this occasion, I would like to wish the Rabbi a good and blessed year, for him and for the members of the site. May we merit that your wellsprings spread outward and be absorbed within us, “and the earth shall be filled,” etc. I would also like to express my gratitude and appreciation for the importance and quality of the things that the Rabbi contributes to our development.
(To resolve the apparent contradiction between a spring and a sea, I would say that for the Rabbi it is in the sense of a spring that flows from itself; for us it is still in the sense of a sea, etc., etc., etc.)
