I'm re-reading Wolf's bio. What a fascinating voice, man, and time and place the world was blessed with. (I almost said "gifted with". Strongly dislike that phrase.) I read a lot nowadays by dipping in here and there. It's easy when the subject is Wolf, as everything is interesting. Such as knives. Every other page seems to have one guy pull a blade on another. Even Wolf carried one. I'm sort of getting a feel for the knife situation in the Chicago blues scene of the late-40s-70s. But I wonder if anyone knows much about the knife culture in other blues styles?
