When you're in the army, a good shovel can come in handy. Especially if you can use it to hammer in tent pegs, dig through walls, saw wood, cut wire and... open wine bottles? In the spirit of the Swiss army knife, comes the Chinese army shovel. And it's pretty cool.

Something to remember when writing, tools can be used for more than one thing. I know assassins, magicians and witches/wise women tend to have multi-use tools (even if it's just a cloak with pockets to hold numerous ingredients). When's the last time you read of a military dude using his shovel as a grappling hook to raid a house? What other multi-tool inventions could people in science fiction and fantasy worlds use?
