I had a question as to the kind of arms the Hashshashin would use. I'm not sure where to look, but all I know is that they used a lot of up-close and personal daggers and blades. Would anyone here know what kind of blades they would've likely used given the time period they existed in?

Question: Are you talking about the Syrian branch, or Alamut branch, of the Nizari Ismailis?

I believe at this period that Syrian swords would have been straight, double-edged cutting weapons. It sounds like this is probably also the case for Iranian arms, but you'll have to ask Manouchehr about them, because he's the real expert on Iranian arms on this forum.
