For one thing, given that the metal blades do as much damage from impact as fusion blaster bolts, and more than nuclear missiles, I'd have to say they're probably very very dense. That's a lot of matter to work with.
For another thing, if you're like me, you'll spew a good hundred of those things out over time all over the battle field. That's a lot of metal floating around in space..
