Steel daggers and their three skins?

Now from what I've seen firsthand each rarity of the Steel Daggers has it's own unique skin.

Blue = Smooth Curve
Purple = Dual tips
Gold = Jagged Edge

I've seen statements made about purple daggers having the gold skin. I'm wondering if anyone would be able to confirm this in game for me? Also I'd like to know if the blue skin has ever been found on a purple or gold set of Steels.

That doesn't really help to answer my question much.

This dagger has three skins:
The skin with a single tip appears to be exclusive to white and blue Steel Daggers.
The skin with a forked tip appears to be exclusive to purple Steel Daggers.
The skin with a serrated back is typically found on gold Steel Daggers, but occasionally purple Steel Daggers may also have this skin.
meaning no one can really confirm anything, sorta like what came first egg or chicken? the best we can do is look at the mass majority.
