Songblades are throwing weapons, comprised of between three and six blades, depending on the sophistication of the weapon, arranged around a central grip. In addition to their cutting edges the blades are shaped for aerodynamic effect, generating lift when thrown in a spin to extend their effective range. The distinguishing features of songblades are the patterns of recesses fashioned into the flats of their blades. When in flight, these recesses cause the blades to "sing", providing an auditory focus point which simplifies the task of a biotic attempting to steer their flight by projecting microgravity fields onto the blades.
Although the concept of the songblade exists in weapons fashioned by tribes across Thessia's northern hemisphere, and parts of the southern - a result of journeying Maidens sharing techniques with foreign tribes they encountered - their actual design can vary greatly. The finest songblades were individually crafted by their wielders, with each blade given slightly different aerodynamic and auditory properties, allowing - with extensive training - an enormous variety of in-flight manoeuvres to be performed. Since huntress acolytes of the period did not benefit from biotic implants, the use of songblades served a valuable purpose in maximising the effect of their limited abilities.
Although songblades are obsolete in the firearms age, their place in asari tradition has ensured that their manufacture continues to the present as a cultural artform. Generic songblades exist, manufactured from lightweight poly-metals which greatly facilitates their use; devotees of the art continue to craft their own unique blades using traditional techniques, and even compete in tests of skill without the use of implants.
The Biotic Games features a songblade contest.
