CJRB Gobi J1906 Guide: Every G10, Titanium and Fat Carbon Build

The CJRB Gobi J1906 is the brand's full-size folding pocket knife: a 3.5-inch folder with a deep-bellied, upswept blade and one of the most comfortable handles in the CJRB range. It has been in the catalog long enough to grow a real family — plain G10, blacked-out PVD, glow-in-the-dark scales, a titanium frame lock, and a 30-piece Fat Carbon limited edition — and the family spans roughly $40 to $200.

This guide walks every current Gobi build in the Artisan Cutlery and CJRB catalog, compares the published specifications tier by tier, and tells you which version makes sense for which kind of carry. Every number below comes from the product listings themselves.

What Is the CJRB Gobi?

CJRB's own product copy names the knife after the Gobi Desert — "the large desert that takes up the majority of the China mainland" — and says the design "takes design cues from traditional knives of desert dwellers." That shows up in the blade shape: a trailing-point, upswept profile with a pronounced belly, which the listing describes as being for "making precise cuts" and for tasks like "filleting fish or skinning small game."

In practice that makes the Gobi a long, slim, all-rounder folder rather than a heavy tactical piece. It is a full-size knife — 8.23 inches (209 mm) open and 4.72 inches (120 mm) closed — but the frame stays compact and the handle is described as having "an ergonomic curve, so you can hold on comfortably for long periods of time."

Blade thickness	0.13" (3.2 mm)

The 3.5-inch blade puts the Gobi right at the point where a folder stops feeling small: long enough for food prep, cardboard breakdown and field dressing, short enough to stay a pocket knife. The G10 Gobi runs 3.7 oz (105 g) while the S90V Fat Carbon version drops to 3.28 oz (93 g) — a real difference you can feel, since the blade length is identical across every build.

The AR-RPM9 builds — the $40–$50 tier

Three of the five Gobis use CJRB's AR-RPM9 powder steel at HRC 59–61. The listing describes it as "our proprietary AR-RPM9 steel that perfectly blends edge retention, corrosion resistance, and ease of sharpening." For a knife that will see cardboard, tape and kitchen duty, that combination is exactly right — AR-RPM9 is a working steel, not a showcase steel. See the full AR-RPM9 line if you want the same steel in other models.

Within that tier the choice is mostly aesthetic and grip-related. The standard contoured G10 version comes in Black, Gray, Green and Natural Green; the coated version pairs the same handles with a blacked-out blade. Both share a steel clip.

The glow-in-the-dark Gobi

The J1906-GD is the odd one out on weight: 3.4 oz (96 g) rather than 105 g, with a plain "G10" handle spec instead of the contoured, CNC-textured scales. It keeps the AR-RPM9 blade and the liner lock, and adds a glow-in-the-dark handle that makes the knife findable on a dark shelf or in a drawer. At $49.99 it sits between the G10 tier and the titanium tier.

The S90V titanium frame lock

The J1906G-TI is a genuine step up: CPM S90V at HRC 60–62, full titanium handle and titanium clip, and a frame lock instead of a liner lock. It is the only Gobi with a frame lock, and it weighs 3.53 oz (100 g) — heavier than the Fat Carbon model, because titanium is not lighter than composite here, it is just metal.

S90V is a high-vanadium Crucible powder steel. The manufacturer's data sheet for its CPM stainless family lists S90V at roughly 9.0% vanadium and about 20% total carbide volume — several times the carbide load of a conventional stainless, which is where its edge retention comes from. The independently maintained steel reference at zknives.com lists the same grade under its CPM 420V aliases, which is also why S90V is slower to sharpen than AR-RPM9. If you maintain your own edges with a guided system, that is a fair trade; if you sharpen once a year on a pocket stone, it is not.

The 30-piece Fat Carbon limited edition

The J1906G-DM is capped at 30 pieces. Same S90V blade as the titanium model, but a Fat Carbon handle, a titanium clip, and a liner lock — and at 3.28 oz (93 g) it is the lightest Gobi CJRB has published. Limited runs at this size are the ones that disappear from the catalog rather than go on sale.

Liner Lock vs Frame Lock on the Gobi

Four of the five builds use a liner lock: a spring-steel bar inside the handle scales that rotates behind the blade tang. One uses a frame lock, where the handle scale itself is the locking bar.

• Liner lock — lighter overall, works with any scale material (G10, glow G10, Fat Carbon), and the lock is fully shielded by the handle.
• Frame lock — fewer parts, and on the titanium Gobi the lock face is a titanium interface rather than a steel insert in a composite handle.

Both are the classic liner lock and frame lock geometries, and both are supported by the same ceramic ball-bearing pivot, so the "feel" difference between the tiers is small. Pick the lock you prefer, not because one is dramatically stronger.

Why the Gobi Makes a Good First Big Folder

• The blade shape is forgiving. A deep belly and a trailing point are easier to use on a cutting board or a box than a hard tanto or a needle point.
• The action is one-handed and flickable. Ceramic ball bearings plus a flipper tab, which CJRB describes as "quick and snappy one-handed flipper deployment and smooth closing action."
• The clip is designed to disappear. CJRB calls it a "polished deep-carry clip that sinks all the way into the pocket."
• It covers a $160 price range. The same handle and blade layout sells from under $40 to $200, which makes it unusually easy to buy the version that matches your budget instead of switching models.
• Warranty is stated on the listing. CJRB advertises a Limited Lifetime Warranty on these knives within the United States market.

Data Notes From This Guide

Two things in the catalog disagree with themselves, and they are worth knowing before you order:

1. The blacked-out Gobi's spec table says D2 and stone wash. The Black PVD listing is titled AR-RPM9 and describes AR-RPM9 in its copy, but its specification block lists Blade Material: D2 and Blade Finish: Stone Wash — both inherited from an older version of the page. The URL slug still says d2-blade for the same reason. Treat the AR-RPM9 / PVD description as the current one and confirm with customer service if the steel matters to you.
2. Weights are published per build, not per model. 105 g, 96 g, 100 g and 93 g all appear for what is sold as the same 3.5-inch knife. Use the weight in the table above for the specific build you are buying, not the general model figure.

Gobi J1906 FAQ

How long is the CJRB Gobi blade?

3.5 inches (89 mm), 0.13 inches (3.2 mm) thick, flat ground, on every current build.

Is the Gobi a liner lock or a frame lock?

Both exist. The G10, glow-in-the-dark and Fat Carbon builds are liner locks; the titanium J1906G-TI is a frame lock.

What steel does the Gobi use?

AR-RPM9 at HRC 59–61 on the G10 and glow builds, and CPM S90V at HRC 60–62 on the titanium and Fat Carbon builds.

How much does the Gobi weigh?

3.28 oz (93 g) for the Fat Carbon S90V build, 3.4 oz (96 g) for the glow-in-the-dark G10, 3.53 oz (100 g) for the titanium, and 3.7 oz (105 g) for the plain G10 versions.

Which Gobi should I buy first?

If you want one knife to use hard, the standard G10 at $39.95 is the value pick. If you want a pocket knife that feels like a tool rather than a toy, the S90V titanium frame lock at $169.99 is the version most people end up keeping. The 30-piece Fat Carbon is a collector's buy, not a workhorse.

Where to Start

You can see every Gobi build on one page, browse the wider CJRB lineup, or compare it against the rest of the Artisan Cutlery and CJRB catalog. If you are weighing the Gobi against CJRB's other full-size models, start with the blade shape: the Gobi's upswept belly is what separates it from a wharncliffe or a drop point, and the shape is the one thing you cannot change later.
