They actually showed Dean being stronger than Crowley. In a episode (i believe Reichenbach) Dean easily shoved Crowley to the floor. I also said "completely immune to the knife". Alastair was immune but he showed little pain. Cain didn't feel any pain at all. I do believe that the Kurdish knife shows results better for demon ranks than the eye color thing.

Plus, Carver you probably ruined the whole "whos more powerful" thing :(.
