Adinary Nuance
A double-edged sword is not the same as a simple problem or benefit. It means the same thing brings both advantages and disadvantages. Writers often use it when one choice looks useful, but also creates risk. It is stronger and more vivid than saying something is just 'mixed' or 'complicated.'
