twoedged

Twoedged is an adjective describing an object or concept that has two sharp edges or two opposing sides capable of producing effect in both directions. In practical terms, a two-edged blade can cut on both edges, whereas a single-edged blade has one sharp edge and one dull side. The term is most often written as two-edged, though older or less formal texts may show it as twoedged without a hyphen.

Etymology and variants: the word forms stem from the combination of two and edged, with hyphenation providing a clear modifier in modern usage. Other common expressions with similar meaning include double-edged and two-edged, all of which describe something that can produce both beneficial and adverse outcomes depending on how it is used or interpreted.

Usage and metaphor: in English-language literature and discourse, two-edged is frequently used metaphorically to denote situations, decisions, or instruments that carry both advantages and risks. The phrase “a two-edged sword” has biblical origins and has entered secular usage to indicate that a policy or technology can yield positive results while simultaneously causing harm or unintended consequences. Contemporary writers often substitute double-edged sword for the same idea.
