My general understanding on the era would be that the lord/dukes/heroes would be allowed their personal weapon as it is kind of their badge of office. Certainly it is not needed for them to carry and being wise, they would most likely have other weapons on their person. That is just my thoughts on the topic.<br/><br/>The honor binding approach is interesting but that seems like an excessive amount of work to place upon the city guard with the arrival of so many persons that would require the thread. Just my opinion anyways.
