Hard, solid block of cheese, hard enough to inflict damage if hit by it. Usually colored in bright shades more typical for taxi cabs than edible matter. For example, Black Diamond.
That block of weapons grade cheese would do some serious damage if you get hit by it.

That's some weapons grade cheese right there.

"Is that cheese or a weapon for self defense?"
"It's weapons grade cheese."
