What is the name given to the pass-grip of a Master Mason?

The pass-grip of a Master Mason is referred to as Tubal-Cain. This name holds significance within Masonic symbolism, as Tubal-Cain is a figure mentioned in the Biblical Book of Genesis, known as a craftsman, particularly of metalwork—a connection to the values of skill and craftsmanship celebrated in Freemasonry. The use of this grip in Masonic rituals signifies trust and recognition among Masons who have attained the Master Mason degree.

Other terms provided in the options, while they have their own meanings and importance within Masonic teachings, are not associated with the specific pass-grip for the Master Mason. For instance, Hiram Abif, a central figure in Masonic lore, is often associated with various rituals and symbols, but his connection is not with the grip itself. Understanding Tubal-Cain's role enriches the meaning behind the practices and symbols enacted during the Master Mason degree.
