Is this a toy

or a very specific and practical tool?  Perhaps you never see but if it wasn't invented the simple would not function?  Ball bearings?  Makes me think of writing.  Without a pencil and its progeny, which  words would have gone unwritten.  Without a mirror, which masks, silent.  Think of the kitchen as a laboratory of invention.  Spoons, spatulas, strainers, saucepans.  Moving away from the beguiling "s" sounds -- can openers, mandolins, rice cooker, knives.  You get the point  No pun intended.
