Well, technically, there IS the Jackknife Dragon line of ancestory, as seen in Jackknife Gift.

Plus, I'm pretty sure Demios might have some relation to Jackknives, because in a few spell cards, it seems to show that he has a helmet with a blade much like Jackknife's, plus, it even shows that it can flip up and down like Jackknife's, because in one art it's down, but in another, it's up, and it shows gears around the blade. In the anime, though, they completely ruined it.

I could be wrong about all of this though, and it's just that they look similar.
