Kind of a random post but something new players or those who do not own a tool box might not be aware of:
Lets use shovel for example. Ever get tired of making multiple shovels to take with you digging? Well, tool box takes care of this for you! When you make a ton of shovels and load them into your tool box the uses on each shovel add up. When you withdraw the shovel you get to choose how many uses you would like to have on that shovel. So say you made 10 shovels with 100 uses on each. After loading them up to your tool box you can withdraw one shovel with 1000 uses on it!
Personally I really like this especially for use with scripts and such so your script doesn't have to keep making shovels or looking for shovels in a storage container = saves time / speeds up the script.
