This impressive katana is made from sturdy E-1187 micron-bots. These make the weapon capable of rebuilding itself when damaged - not as fast as nano-bots would, but with less loss of bots. The blade is powered by a unique set of bio-powered, reversive energy-packs - possibly a SSC product. The energy-packs on this version is broken - and this seems to have crippled the micron-bots in some way. Perhaps the weapon would work again if you replaced the broken packs with new ones.
