This is my idea and design for a sword as I have too much free time on my hands at times.

Jiten-hitokage = rotating salamander
Type: Fire

Sealed: A slightly longer than normal katana with a tsuba in the shape of a flame, the handle is yellow wrapped in red cloth. Other than that it looks like the standard katana

Weilder: Fox (male)

Shikai: Activated by the phrase "Spin" the sword moves out and grows to be about 3 feet from tip to tip. The sword does get much larger but instead the blade will move down and move around the handle to form the curved blade and to envelope the handle in a circle that either one or both hands are capable of holding onto. When wielded with one hand it can be spun around at high speeds in either direction with either hand as its name implies in 360°, and when both hands use it, it can be used and swung about like a normal large blade and slice and thrust into things.

Powers: by slashing through the air it can send out blades of fire and when spun in with one hand it can make swirling vortexes of fire that can be swung and sent out to act as a flaming tornado tearing across the land. It can also be swung in front of the person to send out spinning fire at a distance towards others.

Spirit: The spirit takes the form of a large black salamander with yellow spots.and flames coming out from its back and tail much like salamander spirits are thought to be like.
