Just as a heads up, from somebody who became "famous" for using daggers, they are horrible larp weapons in many people's opinions. In D and D and many other games daggers are a staple weapon for classes such as rogues, but when it comes to live action they are much harder to use. They are much shorter than most weapons the enemies will be using so its harder to get a handle on combat, and to fight with them you have to nearly be "charging" all the time. That is a term you will become familiar with very quickly when you start playing. Essentially if you are fighting too close to somebody in their face you are charging. Daggers are so short that you almost always end up get called for charging which can become a very frustrating thing especially for new players. If you want a short weapon I suggest a short sword at the minimum. That is not to say that you can use daggers if you want, just giving you an experienced players perspective.
