täysteräinen

täysteräinen is a Finnish word that translates to "full-bladed" or "all-steel" in English. It is commonly used to describe a knife or sword that is made entirely of steel, as opposed to one that has a different material for the handle or other parts. This construction is often associated with durability and strength.

In the context of knives, a täysteräinen blade means that the steel extends all the way through the handle, often forming the handle itself or being covered by scales or other materials that are directly attached to the steel tang. This "full tang" construction is generally considered superior for demanding tasks because it eliminates potential weak points where the blade and handle meet, which can occur with partial tang designs.

The term can also be applied to firearms, particularly older designs of bayonets where the entire blade was forged from a single piece of steel. While less common in modern firearms, the concept of a fully integrated steel component emphasizes robustness and a lack of compromise in material integration. The emphasis of täysteräinen is on a singular, unadulterated steel structure for the primary functional part of the object.
