"A short shimmering blue blade extends from a dense black plastic hand-grip."
Very useful for dealing with high AV enemies and digging through walls.
Needs an energy cell to be charged.
IMPORTANT! This is not a general use weapon. Enemies with low AV will take more damage from a normal weapon with normal penetration values. The vibro dagger effectively always rolls exactly the same penetration as its target's AV and will therefore never benefit from large PV damage multipliers against any target.
