Oh literal snap!
|Source:||Dropped when a Mattock is broken.|
|Notes:||Does not do any damage on rebound.|
Once broken, the Mattock head can no longer be used to dig through blocks.
It can, however, still be used as a thrown object. It's even preferable to rocks and such, as it can be thrown without fear of getting hurt if it rebounds off a wall back at the Spelunker.
