what do you call perforated sheet which has been punched to leave a ridge ?
I bought some years ago, but the place I got it from isn't there anymore
need some to repair a machine at work
something where the holes look like the holes in this ?

it needs to be sharp/have grip on one side
I'm searching around but can't fine anything online, and don't want to sound like an idiot when I phone up a few metal places on Monday :-o
