Reply To: Techeiles 🔵❎🐌☑️🐟

I agree that I have no answer to what the Chachmei Umos Haolam. (To quote a very respected poster on this thread: “( and generally speaking [without sparking a huge hashkafa debate] we only listen to these chachmei umos haolam as long as they are not being soiser chachmei yisrael like the radvaz)”)

By the way, I think that you once posted a link to a biography of the Chazon Ish about using Techeiles if there’s a safek. Do you remember where that was?
