I may have a BG42 Bocote coming back to me from the factory. I bought it without a birth certificate so I sent it in to identify the metal. Before I sent it, I took it apart and noticed the blade had no markings on it, which leads me to believe it's BG42. It's old nick design, old pivot. I assume the S30V mnandis are marked S, and the S35VN are marked V, like the sebenzas.
I'll find out when they ship it back to me whether it's BG42 or not!
