Sam: If I tape knives to the edge of the shield, it would become 100% more efficient.

Sharon: Sam no.

Bucky: Yeah, she's right, eventually the knives would fall off. You need something more permanent.

Sharon: THAT'S NOT WHAT I MEANT

Bucky: Sharpen the edges, executes villains immediately. They'll learn to fear Captain America, crime rate will drop. I guarantee it.

Sharon: What?

Sam: The f*ck?

Peter: Like a giant pizza cutter or a murder frizbee.

Bucky: See, he understands.
