The A.D.R.A. (Arditi Distruttori Regia Aeronautica) operated during World War II in the North African territories and were awarderd two silver medals of honour. Today, that unit is known as the 17° Stormo Incursori, a special unit of the Italian Airforce who carry knives of this type. It is a truly extraordinary example of Extrema`s art.

The blade is black BOHLER N690 stainless whilst the handle uses roughened Polyammide. It is supplied in a carry case, with belt and leg sheath.
