Chakram 1 gp 1d6 1d8 x2 30 ft. 1 lb. S
The chakram is a simple, elegant, and highly portable thrown weapon. It is a flat, open-centered metal discus with a sharpened edge.
Benefit: You can wield the chakram as a melee weapon, but it is not designed for such use; you take a –1 penalty on your attack roll with the weapon and must make a DC 15 Reflex save or cut yourself on the blade (half damage, no Strength modifier). You do not need to make this save if wearing heavy armor.
