Talk about an unusual combination of engineering and design! The GRAD TM-Hybrid Knife/Gun is a distinctive piece that brings together two very different concepts in one unconventional design. Combining the appearance and functionality of a knife with an integrated firearm, this is certainly not something you see every day.
How does it function?
The firearm incorporates a six-shot revolver mechanism into the knife handle. The barrel is positioned above the flat edge of the blade, allowing the firearm and knife to share one integrated design.
The revolver mechanism is housed within the handle assembly, rather than being a separate firearm attached to the knife.
Interesting collector information
-
Fewer than 1,000 examples were reportedly produced.
-
It was designed to function as an M16/AR15 bayonet as well.
Its hybrid construction makes it an interesting conversation piece for collectors of unusual firearms, specialty weapons, and unconventional mechanical designs. Rather than being an ordinary knife or conventional handgun, the GRAD TM-Hybrid stands out for its unique combination of form and function.
Unusual, distinctive, and undeniably intriguing, the GRAD TM-Hybrid Knife/Gun is a piece that is sure to get attention in any specialized collection.
How does it work?
According to historical descriptions of the Enigma:
-
It incorporates a double-action, six-shot .22 LR revolver into the briefcase handle.
-
The firearm is integrated into the handle assembly.
-
It uses a revolver mechanism rather than a conventional detachable box magazine.
I can explain its design and historical operation, but I won't provide instructions for operating or firing a concealed firearm built into a briefcase.
The Enigma has also been marketed as an NFA Any Other Weapon (AOW), making its classification and registration history particularly important to collectors.
Whether you're an enthusiast of unique firearm designs, a collector of unusual .22 LR firearms, or simply looking for something you don't see every day, the ASI Enigma is sure to attract attention.
Distinctive, unusual, and anything but ordinary. The ASI Enigma is a piece that deserves a closer look!
