"Cutlery" I always took to refer to knives

Yes, the original meaning was just this, deriving I think from Latin via French (another pure stream, Bob ). The traditional English Guild of Cutlers were specifically makers of cutting implements, and left the making of mere spoons and forks to another guild entirely (the name of which escapes my leaking brain right now!) Someone else will surely fill in... But nowadays cutlery certainly in the UK is taken to refer to all metal table settings. BTW, the most expensive set ever made? Not gold, but aluminum! (or aluminium as it later became known)
