Oh, rest assured the knife was the safely rounded, dull level usually reserved for baby utensils, but stillmetal! No cheap plastic knife bending and flicking things into our face; no cheap plastic fork that bends its prongs instead of sinks them into a bite.
There are of course other airlines out there that still use metal utensils in economy class, but they are fewer and fewer. When you find one, there's a huge chance they aren't skimping on other things either, like nicer soap in the lavatories and better quality blankets and pillows.
So...next place we'll see these utensils? The Dreamliner, duh.
