Just wondering what tools/weapons are good at breaking what? For example: Swords are good at breaking Melons? What? Really? What are the other ones? This is sort of a help question, right?
http://www.ecocitycraft.com/forum/threads/other-uses-of-tools.35918/ Here a guide with more items on each!
If you go to MineCraft Wiki and look for the specific article of a block (i.e Melon, Dirt, Cobweb, etc), the "Tool" Drawing in the first chart will be the one that normally breaks it the fastest (it will also show you if it decreases durability faster).
A very useful tutorial in fact. I just posted my message so they can have a reliable link in case they can't find it quickly on the forums when they need it, or are too lazy to look for it at the Tutorials Section.
