Gravitas Sentry -täytekynä raaka Grade 5 -titaani, rajoitettu erä 2025

The Sentry is Gravitas' larger take on its entry-level pen, and the extra heft doesn't get in the way of daily writing. A weighted, well-balanced section keeps it comfortable in the hand. Turn the cap 2.25 times and the triple-start ACME threads let go smoothly; the delrin sleeve inside the cap protects the barrel surface when you post it.

The 25mm-long section tapers from 13.25mm to 11.5mm and is cut from Stainless Steel, with finely machined circular grooves for grip. Cap and barrel come from a single block of Grade 5 Titanium, so the pen stays light and wears a smooth raw metal finish.

Two o-rings arrived with the recent upgrade: one on the section keeps a tight seal and stops it coming loose when it isn't needed, the other on the barrel guards against the cap slipping off by accident.

Nib duties fall to a Gravitas-produced size 6 steel nib, compatible* with Jowo No. 6 threads, fed by an ABS plastic feeder. Pick from Extra Fine, Fine, Medium or Broad. A standard international plug-in cartridge converter ships with every Sentry.

*If you swap in a different nib unit, checking the fitment is your responsibility - we are not responsible for any damages that may occur from the use of non gravitas nibs/nib units.

Write with it for a week and the balance of that titanium body starts to make sense.
