It's a wrench that can also be a gun

Today for the first time Max made a tool out of lego that is not a gun.

It's a wrench, but it can also be a gun.  Also, it looks like an uppercase "F".

Max: "Dad, look what I made!"
Dad: Rolls eyes, expecting another gun.  Then in a bored voice:  "What is it?"
Max: "It's a wrench!"
Dad: Startled, perks up, puts on a great show of interest:  "Really?  How does it work?  How did you make it?  What do you use it for?  Tell me all about it!"  etc.
Max: Eagerly answers a couple questions.  Then:  "...and it can also be a gun!  Pshew! Pshew!"
Dad: Grabs the nearest pointed object and jams it directly into an eye socket.

To be fair, Max makes many exotic creations out of lego: construction sites, cities, trains, trucks.  But if it's handheld then it's invariably a gun.  Also, the story is funny and the only exaggeration is me poking out an eye.
