Kaksireikäinen

Kaksireikäinen is a Finnish term that literally translates to "two-holed" or "double-holed." It is most commonly used to describe a type of button that has two holes for thread to pass through, as opposed to buttons with four holes or shanks. These buttons are simple in design and are widely used in clothing and textiles for fastening purposes. The two-hole button is a fundamental component in garment construction and is found on a vast array of items, from shirts and trousers to coats and accessories. The number of holes on a button can affect its security and the way it is attached to fabric. Two-hole buttons are typically secured by passing thread through both holes and then through the fabric, creating a secure knot on the reverse side. Their simplicity makes them cost-effective to produce and easy to sew on. The term can also occasionally be used in a more general sense to refer to any object with two openings or perforations, although its primary association remains with buttons.
