rOtring 600 Dark Stone Review: A Handsome New Color on a Classic Drafting Pencil

Introduction

The rOtring 600 has been around since 1986, which makes it nearly four decades old as a product line. This year a new colorway, Dark Stone, joined the range alongside Choco Truff, and Dark Stone has been selling out repeatedly since launch. That popularity is understandable: it is a genuinely attractive finish, and unlike a limited edition it stays in the regular lineup, so there is no need to rush a purchase.

The price is 3,630 yen including tax. Whether it deserves a place in your pen case depends on a few structural details that we get into below.

First Impressions and Design

The Dark Stone finish is noticeably cooler and more subdued than the black version, with something of a lacquer-like character that looks handsome in person even when it is hard to fully capture on camera. Compared side by side with the 800 in black, the difference in tone is clear.

The 600 barrel is brass, which gives it real heft. That cool touch in the hand and the sense of solidity are exactly what you expect from a metal-bodied drafting pencil, and the classic rOtring silhouette holds up well: a hexagonal barrel flowing into a knurled round grip. The knurling deserves specific praise. Some knurled grips are too aggressive and dig into your fingers, others are too shallow and slip, but rOtring’s is close to ideal, delivering confident grip without discomfort.

One design note: this hexagonal-barrel-plus-knurled-grip look makes sense on a drafting pencil, and applying the same styling to ballpoints or multi-pens is a matter of taste. If you love the design and want a matching set in your pen case, the coordinated look is genuinely striking.

Inside the Barrel: Build and Hardware

Internally there is a fair amount of resin, likely to keep the overall weight from becoming excessive. The lead tank has a metal exterior, and the chuck is also metal, and a notably large one, which makes the high durability easy to believe.

The guide pipe is fixed, 4 mm in length. The clip is made of carbon tool steel, a type of steel with ordinary hardness, and carries the rOtring logo. A lead grade indicator window covers grades from 4H to 2B, though the window itself moves rather than the internal marking, which means the window faces front properly only at HB.

The knock cap has a vent hole. An eraser is included, but no cleaner pin. The knock itself is firm with no play, and the balance point sits near the center of the pencil. Full specifications: 142 mm long, 22 g, 9 mm barrel diameter.

Writing Performance

On paper, the 600 is a pleasure to use. The writing feel is very similar to the Staedtler 925 35: the same metallic character, the same faint tactile feedback, the same pleasant scratch you can almost hear. For anyone who enjoys the honest, mechanical feel of a proper drafting pencil, this is the good stuff.

Unfortunately, one flaw gets in the way. The knock cap rattles, and the vibration from writing makes it buzz, with that vibration transmitting to the tip and undermining an otherwise excellent writing feel. For a premium drafting pencil, this is the kind of imprecision that should not be there.

The other quirk is the red ring, a signature of the brand. It spins freely and continuously, feels loose, is not linked to the grade indicator, and does not lock in place. Anything that keeps moving like that can generate vibration, and while this may be forgivable in a general writing pencil, it feels structurally loose for a premium drafting tool.

Things to Consider Before Buying

Summing up what worked well: the design looks great, the writing feel is good, the balance is sensible, the new colorway is attractive, and the grip is stable and slip-free. On the negative side, the knock cap rattles and transmits vibration to the tip, the red ring spins endlessly and loosely, and the grade window would be more satisfying if the internal dial moved instead of the window.

There is a small optical illusion worth mentioning: the Dark Stone’s knock cap looks visibly slimmer than the white version’s, but measuring confirmed they are identical. White is simply a visually expanding color.

Some users address the rattle with tape or similar modifications, which is possible at your own risk, but many prefer to judge the pencil as it comes.

Buying Advice

With a stronger knock cap assembly, the 600 would arguably be a top-tier drafting pencil. As it stands, it offers a superb writing feel, a beautiful new color, and classic metal build, offset by knock cap and ring looseness that precision-minded buyers should weigh carefully. If you are drawn to the Dark Stone finish, check current availability; it has been in and out of stock since release.

Conclusion

The rOtring 600 Dark Stone is a genuinely good-looking drafting pencil with the writing quality and heft the series is known for. Its weaknesses are narrow but real, centered on the knock cap and the free-spinning ring. If you value the design and the writing feel more than absolute structural precision, it is an easy pencil to like.
