razors

A razor is a sharp tool for shaving or cutting hair close to the skin. You also use a razor to cut open packages that are stuck together.

You might have seen a friend with a new electric razor they got for Christmas, or you've probably used a safety razor in the shower yourself to shave your face or legs. Razors are pretty common, and most people need one at some point in their lives. Some people even use them as a metaphor - for example, if someone says that an old job was "razor-thin" on staff, they mean it barely had any employees left!
