kaksiterä

Kaksiterä is a Finnish compound word meaning “two-edged” or “double-edged.” It is used to describe something that has two cutting edges, most often a blade such as a knife or a sword. In everyday language, kaksiterä is typically found in phrases that specify the kind of blade, for example kaksiteräinen veitsi (a two-edged knife) or kaksiteräinen miekka (a two-edged sword).

Etymology and usage are straightforward: kaksiterä combines kaksi (“two”) with terä (“blade” or “edge”). The form is most common in attributive compounds, and the associated adjective stem kaksiteräinen is used to modify nouns. Beyond the literal meaning, the term is also used metaphorically to describe situations, policies, or arguments that carry both advantages and drawbacks, similar to the English expression “a double-edged sword.” In Finnish literature and rhetoric, kaksiterä can thus function as a figurative descriptor for ideas or instruments that have two sides or dual effects.

Related terms include the general concept of a blade with multiple cutting edges and, in translation, the English idiom “double-edged sword.” The usage of kaksiterä emphasizes the dual-edged nature of a blade or a metaphorical situation, highlighting both potential benefits and possible harms.
