Most “ballistic knives” can launch a blade. The Arsenal RS-1 one fire’s bullets.
Technically a firearm in the shape of a knife, this weird weapon is unlike anything else we’ve seen.
Hidden inside the grip is a five shot .22s cylinder (one of the six chambers has been filled to act as a pin rest) with a trigger mechanism that pops out of the grip from the flip of a switch. When not in use, the trigger is recessed flush with the grip.
The shooter in this video thinks he has a mis-fire, but he actually hit the single blocked chamber. All five rounds were fired.
Take a look inside the RS-1 in the video below.
