I like to think that one of the lessons Aizawa taught class A is "always have a knife".

You never know when you'll need a knife so never not be in possession of a knife. As such every member of class A has a knife hidden somewhere in their hero costumes. His gift to them when they graduated were custom engraved knives with their student number on them.

Not on board? Ok. Just imagine how funny it would be tho.

Villain: "Number one hero Deku! I am punch proof! The more you hit me the stronger I get! How will you defeat me now-"

Groupie: "...What?"

Kirishima: "Knife."

Villain, completely insulated in rubber: "You're a one trick pony chargebolt."

Kaminari, reaching down into his boot: "Oh boy are you wrong my dude!"

Hero: "You need to calm down."

Bakugou, reaching down into his V-neck: "Listen here you son of a BITCH-"

Hero: "WHY DO YOU HAVE A KNIFE!?"

Kouda: "Stop scaring the pigeons! They're a domesticated species that we abandoned back into the wild. They're sweet creatures who are pets by nature!"

Douchebag: "Or what?"

Kouda: "..."

Douchebag: "..."

Kouda: "..."

Douchebag: "oh my GOD HE HAS A KNIFE-"
