It is a type of a bearing cluster weapon, using the power of an a several thousands of blades are wrapped within the shell like a spring coil. The blades were made to cut easily and countless numbers of them spread out in the shock of the explosion and rain down on an area of seventy meters.

The shells can be fired by mass produced guns, but trajectories should account for the temperature, humidity, wind direction, and the gun itself, as such only skilled troops should be the one to fire Cutters.

In an ironic twist of fate, the Cutter is used against Roberto Katze himself, along with Hamazura Shiage, Lindy Blueshake, and Leivinia Birdway, by Roseline Krackhart's military volunteers from Pearl Harbor, to secure the President and Lindy more quickly during the Battle of Napali Coast. It only destroys their vehicle's tires however, as is the marines' intention.
