There is also the material science of the rolling ball itself. I assume it has similar constraints to high quality bearings.

- nom 9y agoGood point. But if they can't manufacture ballpoint pens, how can they make bearings? Maybe it's due to their small size?
- ohazi 9y agoThis article is talking about the tip casing, not the actual ball.
- blackguardx 9y agoI took that to mean the ball and the housing around it. The casing would function similarly to a bearing race and the ball to well, a bearing ball.
- blackguardx 9y agoBallpoint pens might be a hard problem. The article didn't say they couldn't make them, it said they couldn't make them as well as others.
