A quick google shows centaur and up having a stack of sloping teeth; pictured cassette has only 1. Agreed it doesn’t look broken (I’d originally thought grime on it was chipping). I’d use it.
I assume that sloped-tooth cog is just out of position on the cassette. It’s arriving with me this week, so I’ll report back and give everyone some closure on this.

@snoops is it an original cog on that cassette?
