Machi-Kanshisha Pipe

Machi-Kanshisha Pipes were long, hollow metal tubes that had been crafted into a pipe. They were most used to smoke herbs, but also be used to deliver a very short-range attack by blowing powder into an opponent's face, most commonly the metsubushi, an irritant that could blind an opponent for short periods of time.

City of Rich Frog
The only common place to find the pipes was in the City of the Rich Frog, where the city guards known as Machi-Kanshisha carried and used the pipes for their traditional recreational purposes, but they were also trained to use them as bludgeons and to strike at an opponent's joints and other weak points.
