The knives aren't so much thrown as launched point-first as if from a railgun, only using Gravity Dust instead of magnetism as propulsion. (Changed from original after thinking about how drawing and throwing the knives from the same prosthetic would work- it would be difficult, if not impossible)

Those names are good (definitely keeping Obsidian Shard), but the knives already have 'Claw' in the name (i.e. 'Wolf's Claws'). Maybe 'Onyx Repulser' as a further reference to Kirito (as in 'Dark Repulser')?
