Katana

The Katana is a common ninja weapon included in many Ninjago sets. It appears as a black sword with a leather wrapped hilt, a very small, flat guard, and a long, thin blade with a slight curve away from the cutting edge.

It is described as a very simple weapon that can be relied upon in combat. There are also gold and silver versions with greater power.

The katana is mainly wielded by the Ninja, but Warriors and Soldiers in the Stone Army also display a preference for it.

Early in Ninjago's run, the katana mold was upgraded, making the blade slightly shorter and straighter. The plastic is also slightly sturdier and shinier than before.

The foot soldier of Ninjago's fighting force, this simple blade is sharp and reliable. While it won't win any beauty contests, it cuts clean and gets the job done.
