The Origin Industries Frame Spear is a YE 31 take on an old concept, that of the infantry spear, made to give the OI-M1-1A Ashigaru a melee weapon with reach. The spearhead is made of ADNR (Aggregated Diamond Nanorods), and has a monomolecular edge, while the shaft is made from Durandium Alloy which is supported by carbon nanotubes (SP8). The spear can shorten through the way of collapsing the shaft in on itself lengthwise, shortening from its full length of 10 meters, down to an easy-carry storage size of 4 meters.
