I have been playing Diablo for the past week and have noticed something strange. I find items (Offhands, Weapons, exct...) that are class speficic and I am not allowed to equip them. (I'm sure they are all horrible for my class anyway.) However I am yet to find anything that is Barbarian specific. Are there any items just for me?

To get a more general overview you can go to the items page on the official Diablo III site and look at all the item categories that are type-specific - as signified by the small class name next to them. You can also click the class in the top bar to see which item types that class can equip (both class-specific and general).
You can (as a Barbarian and only as Barbarian) equip Mighty Weapons and Mighty Belts. However there are two types of Mighty weapons, One-hand and Two-hand.
There's even an achievement about this.
