IWA is the "International Trade Fair for Hunting and Sporting Arms and Outdoor Articles and Accessories". It's the European equivalent of the American SHOT Show (Shooting Hunting Outdoor Trade Show) and takes place in Nuremberg, Germany in mid-March. I don't know if they actually have a sword exhibition per se. You can reach the Nuremberg Convention and Tourist Office at 0911-2336-0 (phone) 0911-2336-166 (fax). HOpe this helps.
