What is the name of the DMC icon/logo?

[WeaverSka]

I'm having trouble finding the logo from DMC.
Remember mission 9, Devil Inside? When you reach Assiel and she has a key.
That thing, the key, which is also the loading icon, and the X360 icon for the games achievements.
Anyone know what its called, if anything, and where there is an image of it?

Thankyou in advance, and forgiveness if I'm just asking dumb questions because I'm new to the DMC universe

Dante also has something like it scarred onto his back.
I don't think there's an official name for it, but it looks kinda like this

Ah yes, I forgot he had it on his back as well. And yeah, its pretty close to that, only differences I can pick up on are the tip of the blade should be more like an arrowhead instead of a straight point, and there was two circles under the main circle on either side of the blade.

Either way, I can use this as a reference picture
Thank you kindly sir

If it counts, I'm sure that's either Sparda's family crest or the game's Rebellion symbol.
