That looks like a genuine INFI Badger Attack TAC (BATAC). That particular knife would have originally been sold through the now-defunct Busse Company Store in late July 2007. Here's a picture of mine for comparison:
It was described on the Company Store website as: "Badger Attack - CG grade, black crinkle with blue-black G-10." It's not at all like the blue-black G10 I've seen lately, and if I didn't know from the description what it was (I still have the email from the BCS), I don't think I'd be able to positively identify it.
They didn't offer multicolor G10 handles on the original BATAC run. That one was a Busse Company Store exclusive that probably sold out in a matter of hours.
