Mezzaluna

If you think I just started making my own words, I did not. This actually is a kitchen tool you will use. Your life will be made simpler. You can chop fresh herbs, pizzas and flat breads easily. No skill required! 

As you can see, this one's a bit old and tired but still works a treat.

You can probably pick one up at any reputable kitchenware store. I found this one http://www.petersofkensington.com.au/Public/MasterChef-Mezzaluna-Chopper-Board-Set.aspx.
