It lets you control how the pen writes: the mechanism adjusts internally to different refill shapes and sizes, and a collet at the front end holds the refill to reduce wobble. ## What are the specs? **Slim, adjustable and metal.** The product page lists: | Feature | Detail | |---|---| | Body | Slim profile, solid metal | | Clip | Reversible, deep carry | | Mechanism | Internally adjustable, auto-adjusting collet | | Refills | 100+ without hacks or modifications | | Extras | Lifetime warranty; free damascus bolt | The page does not give a length, diameter or weight for the slim model. ## Which metal costs what? **Zirconium is the only price jump.** As of October 31, 2026 titanium (stonewashed, black or raw), brass and copper are US$100 each, and zirconium is US$250. The alloys are titanium grade 5, brass HBi59-1.5, copper C11000 and zirconium 702 UNS R60702. ## How does it compare with the Ti Arto? **It trades the refill count for a slimmer body.** The [Ti Arto EDC](https://stationerytimes.com/guides/bigidesign-ti-arto-edc-pen/) lists more than 800 refills against this pen's 100-plus, but uses a screw cap rather than a bolt. Another route to a long-lived pocket pen is the brass [Fisher Space Pen Bullet](https://stationerytimes.com/guides/fisher-space-pen-bullet/). ## What do you give up for the slim body? **A smaller refill list, by BIGiDESIGN's own numbers.** The standard [Ti Arto](https://stationerytimes.com/guides/bigidesign-ti-arto-edc-pen/) lists 800-plus refills and the Slim lists 100-plus, so the Slim fits roughly an eighth as many cartridges. That is still a long list, and it comes with an auto-adjusting collet that the company says reduces tip wiggle. We have not tested any of the refills. ## What does the lifetime warranty and free shipping mean? **BIGiDESIGN advertises both on the page.** The page lists a lifetime warranty with every pen and free worldwide shipping, and says it is happy to help if you ever need anything. We did not read the full warranty terms, so check what counts as covered before you rely on it, as with any maker's promise. ## Who should buy the Slim? **People who find the standard pen thick.** The standard Bolt Action Pen is 9.7 mm across at the barrel and 11.3 mm at the grip, and the Slim is described only as slimmer, with no figure on the page. If you have small hands or write for long stretches, the thinner barrel is the reason to pick it. If you want to put an unusual refill in, the Ti Arto's longer list is the safer buy. ## Where is it made, and what does it cost? **BIGiDESIGN does not state it for this model.** The company is in Chattanooga, Tennessee. Titanium at US$100 is in our $$$$ band (over $75). ## Frequently asked questions ### How is it different from the standard Bolt Action Pen?
