Stiletto is a kind of knife with a slender blade with a well-pointed tip on its end used for stabbing in general, hinting at the actual pistols' accuracy.
The Akstiletto vaguely resemble Stiletto-heels, a narrow high-heeled shoe.
Akstiletto shares common characteristics with the Soma, due to the handles and distinctive vertical/drop-feed magazines.
This is the first Tenno Lab weapon ever released during Update 12.
The lights on the magazines' rear and sides are ammunition level indicators, going dark from the top as the Stilettos fire. However the lights on both Stilettos go off at the same time, despite the guns firing consecutively rather than concurrently.
Using black energy in the Smoke Palette or very dark energy colors will make it impossible or difficult to note the lights on the Akstiletto.
This is the second dual-wield sidearm that currently does not have a single counterpart (being preceded by the Twin Gremlins).
Like the preceding Vipers, the Stilettos make a distinctive sound when their trigger is released.
