Salaams Gonzalo That is a cracking piece of artwork showing the similar dagger form... Brilliantly placed !!

Below examples of the split quilon from the armour clad troopers sword and shown separately a Scottish Claymore sword...with split quilons. Regret unable to find daggers however, perhaps the Mediaeval form on the artwork is a sword?
