No, it cuts through ANYTHING.

Steel, iron, wood, all that.

And bodies.

From the page... and I'll admit I was wrong, but I found out, so are you:
Object displays the ability to effortlessly cleave through any and all dead or inorganic matter, the focal point of this ability being the bristles.
So there. Nyah. But I suppose we should keep it, just in case.

      Build a new site in India, and send 882 and 668 there, research Site 3 coin SCP and develop containment for it.
Also attempt to appease the Hand by allowing 808 to come and go when she wants, as long as she doesn't do anything risky (and train a specialized team to watch her [and maybe even other SCPs] in case she tries anything stupid/dangerous), as well as attempt to appease MC&D by giving them 063 and a few samples of 500, with a note attached saying "Until we have something better- The Foundation".
And last, but not least, send a message to the GOC saying "We cannot destroy them all at this time, as some of the artifacts may be needed to destroy others. However, if you are interested in helping us destroy SCP-668, as well as the dangerous Church of the Broken God, then we may be able to work together. The Foundation. P.S. After all, 'The enemy of my enemy is my friend.'"
Proceed to keep tabs on all the various factions, and see which are truly dangerous to the world, while trying to gain/maintain good relationships with the others.  We're going to need all the help we can get.

Now, can we do all that?

Um... Give MC&D the CotBG coordinates, then send in all agents to finish off the two organizations and retrieve the SCPs. Because I don't want the world to end while I'm playing around with My Little Earth^TM.

THEN proceed to play with the Earth's Mini-Me as suggested above.
