When playing as Aragorn he will come with a sword called "Narsil (Broken)". Keep it until you come to Rivendell. At the Mines Of Moria it will become Anduril. Flame Of The West !
Want to save yourself some trouble in the old forest? Don't make the willow withies you find in Hobbiton into a stick. Keep it and use it to free Merry and Pippin.
All you have to do is drop an item and save. Then you load your game and youll have an extra item.
NOTE: If you try it right when you get the elven potion, miruver, it will diappear.
