What density can I set for Uium, to be reshaped by moon-mass black/white holes

How do you cut through an unbreakable armor? With an all-powerful sword, of course. No really, if we had seemingly unbreakable matter (lets give it the original name of Unobtadamentium, or Uium for short), could we process it with, say, tiny black holes as cutters and tiny white holes as hammers/anvils?

I'm writing a shorty on a typical long-time-ago-galaxy-far-away war, where good-guy and his nemesis must join together to find a way to process Unobtadamentivaibranium - the nigh-indestructible material from which apparently invincible armor and shields - as well as all those wbuilding.stack questions about them - are made.

There are ancient alien structures around the galaxy that were (even longer-time-ago, possibly in a galaxy-farther-away) made from this mysterious Unobtadamentireallystrongium, but no man made tool can shape the material, no man made weapon can even damage it. The powers that be figure that they can make near-invincible space ships, if they can reshape the stuff into such.

I looked at Micro black holes, and White holes and I wonder if they're good candidates for the apparatus to create Uium in the first place, by placing a set of holes on various sides of some material, and using the gravitational push and pull to cram as much density as possible into one point in space. If so, they can be used to reshape Uium, in a similair way.

Assuming white holes exist, and that the apparatus doesn't slip from softish science into fantasy (I know, I know), I'm thinking:

• Micro black holes, each with the mass of our earth's moon, smaller than the size of the dot at the end of this sentence.
• Micro white holes, each with an anti-mass (and resulting grav push) of the moon.
• Uium must be dense enough to withstand a hundred consecutive modern nuclear strikes. It's what comes up in my mind as a good measure for "nigh-indestructible" and "no man made weapon can even damage it". If you have better ideas I'd love to hear them, but bear in mind that sending the stuff into the sun, or striking it with a bazillion gazillion nukes, is not practical. Uium must have some breaking point for it to be processed, but not a crazy overkill (just some general relativity tweaking..)

My question is: What would be a viable black or white hole density to Uium density ratio (or in other words, what density can I set for Uium)?

Edit: The guys aren't able to create black holes, I'll decide later on how much they're capable of getting their hands on such and manipulate them. Might decide that they only find the documentation on the ancient aliens' methods of dealing with Uium but sigh in despair upon realizing that these methods are beyond current human tech.
