An Honour Blade is a two-handed T'au close combat weapon utilised exclusively by members of the Ethereal Caste. Honour Blades, whilst custom-made to each individual, all consist of a long, broad-bladed halberd mounted on a lightweight metallic shaft.
Honour Blades serve as symbols of an Ethereal's office, ceremonial weapons and, in emergencies, weapons of self-defence. Honour Blades are typically used to settle disputes between Ethereal Caste members in highly stylised, bloodless duels that are more coordinated co-meditation than combat.
In the hands of an Ethereal, Honour Blades are used in elegant sweeping movements where the blade becomes virtually invisible. Whilst some Ethereals carry their Honour Blade onto the field of battle, they do not expect to have to actually use them, but are nevertheless prepared to make a last stand against their barbaric foes if the situation should require it.
