I think both of those statements are correct. I have two .22" thick satin BJs that are marked "PROTO" without the blood groove, so not all BJ prototypes have a blood groove....
Additionally, I have told only the Boss Jack Prototype knives have blood groove in blade. Regular production Boss Jack knives did not have blood groove in blades.

That is about it.Dang it.... I've never wanted a Boss Jack, but this thread has changed my mind! What a cool profile! Somebody sell me a bossjack... lol
So.... what is the purpose of a fuller on a blade? Is it just a weight reduction?
