I wasn't surprised. When I heard they ran a custom knife shop I was impressed. Then as I continued to watch (including the clips from the knife shop) I realized they were 19. I mean, I knew they were, but it really showed. One thing about this show is it (surviving that is) seems to strike a balance between youthful ability and mature wisdom. The young man who fell while carrying an ax with no sheath is another good example. That's why there are sayings like "you live and you learn."
