New Arrivals: TWSBI Precision "Gemini Blue" Fountain Pens, and a Small T.G.S. x Sunderland Restock

It’s finally here: TWSBI has released the Precision fountain pen in a new “Gemini Blue” color to complement the Gunmetal finish that has been a staple of the TWSBI line for years. In addition to the new Gemini Blue, we have additional Gunmetal Precision fountain pens plus TWSBI’s excellent Precision Ballpoint pens, Precision Mechanical Pencils, and TWSBI Pagoda Jr pencils (which are a steal at the current pricing). Available for purchase as of today.

The T.G.S. x Sunderland Machine Works collaboration mk1 rollerball is an excellent everyday carry. You can read more about this release in a past post explaining the thought behind it. We plan to do more with Sunderland in the future!

Finally, we have a special announcement: A small handful of additional T.G.S. x. Sunderland Machine Works collaboration pens. (It’s a very small number, representing some spares from our last run.) We likely won’t do another run of these specific pens for a while, as we want to focus on other projects such as our latest release/collaboration with Hinze Pens, but stay tuned because we have more Sunderland coming!

The Gentleman Stationer is supported entirely by purchases from the T.G.S. Curated Shop and pledges via the T.G.S. Patreon Program. Please note that our Brick and Mortar hours are slightly modified this week, and we will be closing an hour or so earlier each day due to some work that I have to do both in and out of the shop.

Pen Review: The TWSBI Precision Fountain Pen

Despite epitomizing so-called old technology, do you know what product continues to be enduringly popular? The woodcase pencil. Do you know what else tends to sell insanely well, though they’re a bit more of a cult taste? Hexagonal pens designed to mimic the feel of the pencil. Often marketed as “drafting” or “technical” pens, these are one of the most heavily requested products, both for review purposes and for the shop. The now-discontinued Rotring 600 fountain pen remains the darling of this category, yet for years TWSBI has sold a fountain pen version of its “Precision” line. I can’t believe I’m just now reviewing it.

Hexagonal Pens: They’ll never roll off the desk! The TWSBI Precision fountain pen, second from right, shown with the Caran d’Ache 849 Paul Smith (top), the Rotring 600 (right), the Mark’Style Days Metal Gel Ballpoint, an the TWSBI Precision Ballpoint/Mechanical Pencil (far left).

I first got my hands on the Precision ballpoints and mechanical pencils last year. I loved them both and they are constantly in my “go-anywhere” rotation, especially when I’m working and need a reliable, understated no-nonsense writing instrument. The Precision fountain pen is a larger take on the same format, with brushed “gunmetal” construction that assumes as understated a look as a fountain pen like this one can possibly have. I do appreciate added texture on metal pens: this one feels especially good in the hand with excellent balance and just the right amount of “grippiness” to prevent slippage.

Something about a technical pen gives you an increased sense of … precision… especially when writing or annotating. I opted for a fine nib on the fountain pen, and I’ve been using it regularly to take smaller notes. The nib is the same as on the TWSBI Diamond 580, though you will need to swap the nib manually (friction fit) as I’m told the nib units are designed slightly differently.

Though traditionally intended for “technical” professionals such as architects, there’s no reason you can’t use a so-called drafting pen for everyday writing. The Precision writes comfortably due to the rounded section (no knurling here), and I’ve found the pen to feel best unposted. That said, the piston knob/blind cap on the back of the pen does come equipped with a double set of o-rings to allow you to post the cap securely, and while a touch long for my taste, the pen certainly remains usable.

Like most TWSBI fountain pens, the Precision fills with TWSBI’s reliable piston mechanism, and this particular model includes an ink window just above the section threads so you can monitor your ink level. Here the Precision borrows from the TWSBI “Classic” - yet another TWSBI back-catalogue item I’ve never reviewed. While the Precision doesn’t hold as much ink as the TWSBI ECO or the Diamond 580, you’ll still get a significant amount of writing from each fill. I’ve had this one inked for a couple of weeks and it’s not run dry on me yet despite fairly heavy use at work. As noted above, the pen sports the same nib as the Diamond 580, and offers the same reliable writing experience.

Takeaways and Where to Buy

The TWSBI Precision reaffirms, once again, my decision to spend some time revisiting companies’ “back catalogues” and reviewing older models that I bypassed in the early days of T.G.S. The Precision is an excellent fountain pen, especially for $80 (compared to $300+ for some of the vintage Rotrings), making it a great way to try out this type of writing instrument. The nibs are standard TWSBI Diamond 580 nibs, though the nib units are slightly different and you will need to swap the nib directly (by pulling and replacing) rather than using the Diamond 580’s threaded nib unit. The design offers TWSBI fans and/or those looking for a reasonably priced “technical” fountain pen something quite different to add to their rotation.

I’m somewhat surprised TWSBI has not expanded the Precision fountain pen lineup with at least one or two other colors, such as standard black and silver to match the ballpoint and mechanical pencil. Given the demand for this type of fountain pen, and Rotring’s exit from the technical fountain pen market, there should be a natural opening, and that brushed metal finish would look exceptionally good in multiple colors.

Technical Pens and Pencils: The TWSBI Precision Ballpoint and Mechanical Pencil

So-called “drafting” pens and pencils are sometimes considered a category unto themselves, or as a subset of the slightly broader “technical” pen and pencil category. Long-dominated by the beloved (and excellent) Rotring 600 and 800, many companies have shied away from introducing their own version of this classic piece of stationery kit, despite it’s enduring popularity. Not TWSBI, who over the years has introduced four different mechanical pencils, two ballpoint pens, and a technical-style fountain pen through their “Precision” line of products. Today I’ll take a look at the Precision mechanical pencil and ballpoint.

The Precision Mechanical Pencil comes in both fixed and retractable-pipe versions.

So What Distinguishes the TWSBI Precision Line of Pens?

If you (like me) already own multiple Rotring 600 and Rotring 800 pens and mechanical pencils, what differentiates the TWSBI Precision to the point that you might want to give this particular pen and/or pencil a shot? Here are my main points to consider:

• Different Knurling on the Grip. The primary difference I would highlight is the knurling (or grip texture), because this aspect will likely affect your everyday writing the most. Rotring uses a rougher, almost sandpaper-like texture that people either love or dislike depending on whether it hurts their fingers. Personally, I’m a big fan of the Rotring grip, which I think gives the pen a tactile writing experience that’s not duplicated elsewhere, but I also enjoy TWSBI’s approach. The Precision grip appears to be molded into the barrel as opposed to machined, so the knurling is slightly more raised and can have a softer feel. It all comes down to personal preference.

• Slightly Softer Edges on the Hexagonal Barrel. I’ve never noticed it until this direct comparison, but the edges on the Rotring pens are pretty sharp. The TWSBI Precision is more rounded, akin to the Caran d’Ache 849, though I would place the Precision “in the middle” between the other two.

• Different Aesthetics. Rotring famously adheres to a black/silver + red color scheme, and though they’ve moved away from that in recent years with a few new base colors, the overall aesthetic remains consistent. I would characterize the finish on the TWSBI Precision as more “satin” as opposed to Rotring’s true “matte”, and the TWSBI’s chrome clip, knock, and tip look nice on either the black or silver pen/pencil.

• Different Mechanism on the Retractable Pipe Mechanical Pencil. I previously reviewed the Rotring 800, and I love how that pen features a twist mechanism on the knock that allows you to retract the sleeve / “pipe” for pocket carry. The TWSBI Precision has a similar feature, though you need to depress the knock and press down gently to get the pipe to retract. It’s less convenient, but it’s also a less expensive pencil.

The knurling on the TWSBI Precision (top) and the Rotring 600 (bottom) is very different. One is not better than the other - they just have a completely different feel. Note that the tip on the TWSBI Precision ballpoint extends slightly farther than on the Rotring 600. Personally, I like this because I enjoy more needle-tip pens that feel as though they provide more control over my writing. Others prefer how the Rotring looks.

General Functionality and Writing Experience

Overall, the Precision provides a very nice writing experience for the price point. The Precision pens and pencils are approximately the same weight and length as the Rotring 600, and slightly shorter/slimmer than the Rotring 800. Due to the different texture, the feel in the hand is more akin to the Caran d’Ache 849, and those who appreciate the 849 line of writing instruments but find themselves wanting a more textured grip section and slightly longer barrel should consider the TWSBI Precision.

While the pens discussed here all share certain design elements, they have their own unique feel in hand and will appeal to different users in terms of both aesthetics and functionality.

Though not a game changer, I wanted to point out that TWSBI adds value by including a pack of leads and replacement erasers with the Precision mechanical pencil, and a second Parker-style ballpoint cartridge with the ballpoint pen. The erasers are a cool touch - they’re super long, do their job well, and should last you for a while. The TWSBI-branded ballpoint refill is quite nice, but if you prefer something else it’s Parker-style so you can swap in your choice of the endless Parker-style ballpoint/gel/capless roller refills out there.

I love the long eraser on the TWSBI Precision. Plus you get three of them, likely enough to last you years unless you really enjoy your mechanical pencil erasers.

Takeaways and Where to Buy

To be perfectly honest, now that I’ve been using my own Precision ballpoint and Precision .5mm retractable mechanical pencil for a couple of months now, I’m kicking myself for having waited this long. In my opinion, TWSBI doesn’t do a great job of promoting their non-fountain pen product line, and even though many people have commented about how nice their mechanical pencils are, it’s one of those products that I put off trying and reviewing for years. I’m now wondering whether it’s time to pick up a Precision fountain pen.

Three different pens/pencils, three great options: the Rotring 600 (top), the TWSBI Precision (center), and the Caran d’Ache 849.

We recently added the TWSBI Precision line to the T.G.S. Curated Shop, and currently stock both the Precision Ballpoint and Precision Mechanical Pencil in all colors and subtypes. As noted above, the mechanical pencil is available with both .5mm and .7mm lead sizes, with a fixed or retractable pipe. Both Precision Ballpoint Pens and Mechanical Pencils are priced at $25, which I personally consider a very fair value.

New Arrivals: TWSBI Precision Ballpoint Pens and Mechanical Pencils

Fans of technical pens and mechanical pencils will appreciate TWSBI’s “Precision” line, which feature all-metal construction and a comfortable, softly-knurled grip. The mechanical pencils come in eight different variations: both matte black and silver finishes, .5mm and .7mm tip sizes, with either fixed or retractable pipes. As with all things TWSBI, both the ballpoint and the pencils represent good value, priced at $25. The pencil ships with both replacement erasers and leads, and the ballpoint ships with an extra Parker-style refill. Available for purchase now in the shop!

(For my own personal set, I’ve of course chosen the matte black finish with the .5mm retractable tip.)

The TWSBI Precisions aren’t the only “drafting-style” pens and pencils that we carry. For shorter, pocketable versions, check out the Penco Drafting Pens and Drafting Pencils.
