  In our solar system, most small stuff has been rounded by billions of years of collisions. This may be a primeval shard from a high-energy collision in another solar system - unaffected because it was flung out of that system at high speed. Cosmic pointy shrapnel. :) (Big stuff self-rounds per gravity, of course, but this ain't that big)
