Leather belt, which is well suited for re-enactment, or for tournaments in armor. This is a required attribute of a knight, and we made it practical for fighting. It is simple, made of sturdy leather with a brass/stainless shank and buckle. We installed a mount on it for spare weapons. So you will not be left unarmed in buhurts.
Just get it and continue the fight.
Especially convenient for fighters with two-handed weapons.
