Terätty
Terätty is a Finnish word that translates to "sharpened" or "tempered" in English. It is commonly used in the context of blades and tools, referring to the process of making an edge keen and durable. This process typically involves heating the metal to a specific temperature and then rapidly cooling it, a technique known as hardening. Following hardening, the metal is tempered by reheating it to a lower temperature and allowing it to cool slowly. This tempering process reduces brittleness while retaining hardness, making the tool more resilient to wear and impact.
The term "terätty" can also be used metaphorically to describe a person's mental state or skills that
