Blyantenkniven

Blyantenkniven, also known as a ballpoint pen, is a type of pen that uses a replaceable cartridge containing a refill of ink. The term "blyantenkniven" is a Swedish word that translates to "ballpoint pen" in English. The pen was invented by László Bíró in the 1930s, and it quickly gained popularity due to its convenience and reliability. The ballpoint pen operates by using the pressure of the pen's tip against the paper to force ink onto the page, rather than relying on a nib or fountain system. This design allows for a consistent line width and eliminates the need for frequent refilling or maintenance. The ink in a ballpoint pen is typically water-based, which makes it less likely to dry out or clog compared to other types of pens. Blyantenkniven is widely used in various settings, including education, office work, and personal use, due to its durability and ease of use.
