This is purely idle curiosity, but: has there ever been an instance (in any format) where Batman's utility belt doesn't contain the item he needs to solve a problem? (The answer was not obvious from a quick web search.)

    In The Dark Knight it sure didn't have a stop-your-girlfriend-being-blown-up button. Apr 24 at 22:43

    The thing is, he would know it's not there and not look for it, so it's not made a point of.

    I could certainly imagine a plot point like "oh no! I forgot to pack the Bat-cheese to distract the giant mice!"

    I vaguely remember instances of Batman suffering a defeat against a new foe, going back to his lair to better prepare, then winning the next fight thanks to new tailored gear. For instance, adding heat-insulation to his suit to confront a fire-based opponent, adding electricity-insulation to his grappling hook to confront an electricity-based opponent, etc.

    It seems like almost any situation where Batman has a failure or setback would qualify here. He didn't have a back-brace for his first fight against Bane, he didn't have hacking equipment for his first fight against Prometheus, etc. Apr 25 at 20:10

As per ScreenRant, in Batman/Superman Vol. 2 #18 (2021) it's revealed he did not have a cauterizing iron.

relevant Batman/Superman Vol. 2 #18 panels

Using his laser vision to cauterize Batman’s heavily wounded shoulder, Batman proceeds to pull out what is more or less an entire first aid kit from his utility belt to finish up dressing his wounds, prompting Lois to ask the question all readers constantly wonder about The Dark Knight: what doesn’t he have in that nifty belt of his? Responding with the obvious answer after Superman’s help, Batman simply answers by saying, “A cauterizing iron,” as he quickly brushes over the fact that if Supes wasn’t around to staunch the bleeding with his heat vision, Batman might not have made it out of their situation alive.

    He's probably just trying to make Supes feel useful.

    One must draw the line somewhere between "will I ever need this" and "this belt is getting impractical and unwieldy"...

    @DavidW yes, that's the correct interpretation. I bet Batman had thermite in his belt and a screwdriver in that very moment, add both together and here you have your cauterizing iron. Apr 25 at 12:47

    @MindwinRememberMonica: That raises the point of using up a consumable item (like thermite): another reason to use something else if you have time. Apr 25 at 17:22
