Ferrum Rescue has a thin and compact shape, its anodized anticorodal aluminum handle scales making its grip light, slim as well as resistant. It can be placed in a pocket, in small flashlight holsters or in a single M.O.L.L.E. system webbing. It is also equipped with a hard-metal glass breaker on the bottom part. It comes with a flipper assisted opening. The blade rotates on ball bearings resulting in a fluid and firm movement. This mechanism allows the user an easy and rapid opening of the blade, even with just one hand. The locking mechanism is the time-tested liner lock.

The reversible clip is located on the back. Ferrum Rescue is available in two versions, Red and Black; the first has a clear rescue connotation as it helps the user find the knife in the event of a fall. The second has a more tactical and less conspicuous feature.
