The Amazing Pickaxe mod adds a new magic pick that will not only be able to break the block, but also to return it to its original form, for example, if you break a block of iron or gold then they will not drop a drop, and a regular block will appear again that you can put in inventory and use it as you please.

     The pickaxe will return the blocks to their normal form when you press the right mouse button, if you press the left block, it simply disappears.
