IS a French Can Opener a thing? Are you going to tell those of us who can't figure it out? This is my review: Harry Potter #8: Let's try that again, shall We? Yes, I'm saying it's that good.

I have no idea whatsoever! If some French person comes along and tells me they do, in fact, have different can openers over there, I will insist that it is a name like "french fries" or "french horn".
If a character claims they know, you should be skeptical of them. :)
