Cypher does have it i believe, its always sheathed and apparently he's heading closer and closer to Terra.
Cypher isn't his real name as well Cypher was the title given to the Dark Angel who is guardian of all the old traditions, if you read Descent of Angels.
The first part is what was said in the old Dark Angels codex and its what i believe to be true, the second part is what i gained from Descent of Angels it can't be a conincidence that the guy with the traditional sword is the name of the rank who guarded the traditions.
