CJRB Gobi Family Guide: From Budget AR-RPM9 to S90V Titanium Exclusives
Every CJRB model family has a personality, and the Gobi's is written into its name. It takes cues from the desert — an upswept, deep-bellied trailing-point blade that CJRB originally pitched at precision tasks like filleting and skinning small game, wrapped in ergonomically curved handles. But the Gobi story is really a price-tier story: the same 3.5-inch platform runs from a $39.95 G10 workhorse to $199.99 limited-run S90V exclusives, with a titanium frame lock sitting in between.
That spread makes the Gobi one of the best models for understanding how CJRB scales a design from budget steel to premium materials. This guide walks through every current tier, what changes between them, and which version is actually worth your money.
If you are new to the brand, our CJRB buying guide covers the full lineup, and the AR-RPM9 steel guide explains why this steel became CJRB's budget workhorse in the first place.
The Gobi Platform: What Never Changes
Every Gobi shares the same core geometry and construction, which is what makes the family comparison clean:
Blade. 3.5 inches (89 mm) of upswept, trailing-point blade with a deep belly and a flat grind. The belly gives you long, slicing strokes; the upswept tip keeps the point controllable.
Pivot. Ceramic ball bearings across every version — budget G10 and premium titanium alike. Flipper deployment is the primary opening method, and on the budget models the action is genuinely good for the price.
Lock. This is where the family splits. The G10 versions use a liner lock, while the titanium exclusive switches to a frame lock with the lock bar cut into the handle itself.
Size. Overall length is 8.23 inches (209 mm) with a 4.72-inch (120 mm) closed length — a full-size folder by any measure, roughly in the same pocket footprint as the Feldspar and Crag. Weight runs 3.3 to 3.7 ounces depending on handles.
Blade thickness. 0.13 inch (3.2 mm) across the family — noticeably sturdier stock than a slicer like the CIVIVI Yonder's 0.09-inch blade. The Gobi is built for work, not just mail opening.
The deeper belly and upswept tip are worth understanding before you buy — blade shape determines a lot of real-world feel. Our blade shape guide explains the tradeoffs, and the frame lock vs liner lock comparison covers the locking difference in detail.
Tier 1: Budget G10 in AR-RPM9 ($39.95-$49.99)
The entry Gobi comes in contoured G10 with a CNC pattern texture on the handle, stonewashed AR-RPM9 blade, and a steel pocket clip. Hardness runs HRC 59-61. At $39.95, it is one of the cheapest full-size folders CJRB makes (product page).
From there the budget tier branches into color and finish options at the same ~$42-50 price:
- Black PVD blade version for a stealthier look, $42.49 (product page)
- Glow-in-the-dark G10 with a stonewashed AR-RPM9 blade, $49.99 (product page)
The glow-in-the-dark version is the personality pick of the whole family. The G10 scales absorb light and emit a soft green glow at night, which makes the knife easy to find in a dark bag or tent — a genuinely useful trait, not just a gimmick.
About AR-RPM9. This is Artisan Cutlery's in-house budget steel, and it deserves an honest paragraph. The name suggests a powder-metallurgy "rare powder material," but independent metallurgical analysis — including testing covered by Knife Steel Nerds — found the composition is essentially a spray-formed version of 9Cr18MoV with roughly seven alloying elements rather than nine. The practical takeaway: AR-RPM9 performs like a competent budget stainless, similar to 440C-class steels. It sharpens easily, resists corrosion well, and holds an edge acceptably for light-to-moderate use. It is not D2-equivalent in wear resistance, so set your expectations accordingly. Knife Steel Nerds' broader steel ratings by a metallurgist is a good reference for where it lands.
Tier 2: The S90V Titanium Frame Lock ($169.99)
The first big jump in the family is the J1906G-TI: the same 3.5-inch upswept blade, now in CPM S90V at HRC 60-62, riding in a titanium handle with a frame lock. Weight comes to about 3.5 ounces (product page).
S90V is a high-vanadium powder steel famous for edge retention — it is one of the longest-wearing stainless steels you can buy, at the cost of being harder to sharpen and less tough than simpler steels. It is a material for collectors and dedicated users who value holding an edge over quick touch-ups. Our S35VN vs S90V comparison and the which steel holds an edge longest ranking put it in context.
The titanium handle changes the character of the knife. Titanium scales feel warmer than G10, the frame lock removes the separate liner, and the whole package picks up a premium feel that the $40 version can't match. If you already own the budget Gobi and love the blade shape, this is the "same knife, entirely different class" upgrade.
Tier 3: The Limited Fat Carbon Run ($199.99)
At the top of the family sits the J1906G-DM, a 30-piece limited run in Fat Carbon handles with the same CPM S90V stonewashed blade. It's a liner lock rather than the titanium version's frame lock, and at about 3.3 ounces it's actually the lightest of the premium pair (product page).
Fat Carbon is a resin-infused carbon fiber with a distinctive marbled, flowing pattern — every knife in the run looks slightly different. That, plus the 30-piece cap, makes this the collector's Gobi. Limited runs like this are the model for our budget knife collecting guide: buy it because you want the material and the scarcity, not because it cuts better than the titanium version — the blade steel is identical.

All versions: 3.5-inch upswept flat-ground blade, ceramic ball bearings, flipper opening, 8.23-inch overall length.
Which Gobi Should You Buy?
Budget pick: the plain G10 Gobi at $39.95. It is a full-size, bearing-driven folder with a genuinely distinctive blade shape for less than a dinner out. If you want the color or a non-reflective blade, the ~$42-46 finish variants are worth the small bump.
The fun pick: the glow-in-the-dark Gobi at $49.99. Same knife as the budget version, but the glowing G10 makes it easy to find at night — and it's the version people ask about.
The upgrade: the S90V titanium frame lock at $169.99 if you want premium materials and the strongest lock in the family, or the 30-piece Fat Carbon limited at $199.99 if you collect. For a first knife or general hard use, the extra $130-160 for S90V is hard to justify — budget AR-RPM9 covers most daily cutting, and the blade shape is identical.
FAQ
Is the CJRB Gobi a good knife? Yes, particularly at the entry price. The Gobi is a full-size 3.5-inch flipper with ceramic bearings, a distinctive upswept trailing-point blade, and a liner lock in G10 — solid construction and good action for $40-50. Higher tiers upgrade the steel to S90V and handles to titanium or Fat Carbon.
What steel is the CJRB Gobi made of? Budget Gobi models use AR-RPM9 at HRC 59-61, Artisan Cutlery's in-house stainless that performs in the 440C-class range. The premium J1906G-TI and J1906G-DM exclusives use CPM S90V at HRC 60-62, a high-edge-retention powder steel.
Is the CJRB Gobi a liner lock or frame lock? It depends on the version. The G10 and Fat Carbon models use a liner lock; the titanium J1906G-TI exclusive uses a frame lock, with the lock bar integrated into the titanium handle.
How big is the CJRB Gobi? The Gobi has a 3.5-inch (89 mm) blade, an 8.23-inch (209 mm) overall length, and a 4.72-inch (120 mm) closed length. It weighs roughly 3.3-3.7 ounces depending on handle material.
What is the difference between the Gobi J1906 and J1906G? J1906 designates the standard AR-RPM9 G10 versions ($39.95-49.99). The J1906G models are the premium exclusives — J1906G-TI with a titanium handle and frame lock at $169.99, and the 30-piece J1906G-DM Fat Carbon limited at $199.99, both in CPM S90V.
