Dragon's Tooth sword (DX)

The Dragon's Tooth Sword is a weapon consisting of a nanotechnologically created blade, which is dynamically 'forged' on command into a non-eutactic solid. Nanoscale whetting devices ensure that the blade is both unbreakable and lethally sharp. It was developed in VersaLife's Hong Kong laboratories and was used to help start a war between two prominent Triads.
