Ok. So, I decided to start doing some deep mining today in minecraft, and I found a LOAD OF REDSTONE. Im so happy because I've been looking for this stuff for hours and I want to mine it. The thing is I used an iron pick and it didnt work right ( it destroyed the block without giving me the redstone ) and I'm afraid to use it again because I don't want to loose any of it. Is there a special kind of pick axe I'm supposed to use?
