Machined from 6061-T6 aluminum, the Bolt features a pared-down, industrial aesthetic. It operates like a traditional click pen with a twist: The tip is deployed by way of a simple push and turn of the bolt mechanism on the end of the pen.

The standard Bolt is compatible with Parker-style refills only, though it’s capable of being modified for compatibility with other, shorter refills using the included plastic tubing. The Bolt G2 uses the popular Pilot G2 refill and features a longer front barrel section. For convenient carrying, both are fitted with a stainless steel clip, which can be removed with a hex key.
