Bullet Ant Titanium Bolt Action Pen + Bit Driver
This unique pen has a built-in bit driver in its rear end. It’s made from CNC-machined GR5 titanium, and its bolt-action mechanism deploys in two directions – one for the pen and the other for the driver bit. It includes ten alloy tool steel bits and has internal storage for two of them. Accepts off-the-shelf Lamy M22 refills.
