A hossu is a ritual staff of wood with bundled hair (real horsetail) wielded by a Zen Buddhist priest.
The stick is believed to protect the wielder from desire and also works as a way of ridding areas of flies without killing them.
- Often described as a "fly swatter" or "fly shooer"
The hossu is regarded as symbolic of a Zen master's authority to teach and transmit Buddha Dharma to others
- And it is frequently passed from one master to the next.
