The bunrai is a type of ninja weapon that is similar to a Scythe. It began as a farming tool used to thresh grain. It was reevaluated as a weapon by farmers and ninja.
It first appeared in Baxter's Gambit when April tried it out and had to be saved by Splinter when she nearly killed herself with one. In Showdown, Raphael armed himself with weapons, including the Bunrai.
- In Korea, this weapon is called the sonjibon.
