Siangham

A siangham is an exotic light melee weapon used mainly by monks.

Description
The siangham looks like a heavy metal arrow with a hilt or handle where the feathers would be. It is about a foot and a half (46cm) long with a piercing tip. An average siangham costs 3gp and weighs 1lb (0.45kg).

Weaponology
It takes special training to use a siangham in melee combat, therefore it is considered an exotic weapon. While normally used for thrusting attacks, it can be used to slash or parry.
