I guess it comes down to what you consider Masonic Secrets. I've never met anyone who considered the working tools (or even the majority of the Tracing Boards) as secret.My interpretation. If brothers in my jurisdiction have them, they're not openly displaying them at any of our meetings/outings. Maybe, I just haven't paid attention. I'm really not trying to be the tattoo police. I have not seen anything in writing that prohibits them either.
