Oftentimes on buying items like faucet water filters, they'll say something like "Chrome finish." Are they really finished with a chrome coating, or is that oftentimes just used as a color-indicator? Aren't chrome usually very expensive? Are such names usually indicative of another metal instead?

Take a pencil. A pencil sharpener that reproduces the same exact sharpening result. A sharpened pencil has graphite lead protruding in the shape of a cone.
