Don't know that the Masons ever carved the symbols in the flesh, but I don't think the Mormons did. They did used to cut the marks in the fabric in your first set.
No actually, they carved the symbols into your flesh back in Joseph Smith's day. When Smith decided to make the women take the endowment, in the hopes that the threats of disembowelment and throat slitting, would keep them quiet on polygamy, Ema refused to have your breasts cut. Smith compromised, after she suggested that she could wear the symbols, stitched in red thread, on her underclothes. This was the birth of the Mormon garment. Steve Benson did a whole thing, with all kinds of links and references on it about a year or so ago.
