Custom rolling ball pen pilot precise grip Manufacturer The rolling ball pen, also known as a ballpoint pen, was patented in 1888 by John J. Loud. However, it wasn't until the mid-20th century that the pen gained widespread popularity. The modern rolling ball pen owes its existence to the efforts of László Bíró, a Hungarian journalist, who, along with his brother György, patented a new type of pen in 1938. Their design addressed the issues of ink leakage and inconsistent flow that plagued earlier models. At the heart of the rolling ball pen is the ballpoint, a small sphere that rolls across the paper, transferring ink as it moves. The ball is typically made from a hard, durable material to ensure longevity and smooth operation. Materials such as tungsten steel and stainless steel are commonly used due to their resistance to wear and their ability to maintain a consistent shape over time. The choice of material for the ballpoint is crucial for the pen's performance. Tungsten steel, for instance, is known for its high hardness and resistance to deformation, which makes it an ideal choice for the ballpoint. Stainless steel, on the other hand, offers a balance of strength and corrosion resistance, ensuring that the ballpoint remains functional even in challenging environments. https://www.gelpenfactory.com/product/ballpoint-pen/
