There are plenty of ways to make a folding knife look different. The harder trick is doing it without making the knife unfamiliar to use. That is the problem the CJRB Nova tackles.

Its blade is anything but anonymous. The angular tanto profile and harpoon-influenced shape immediately separate it from the rows of conventional drop points competing for EDC pocket space. Yet the controls are deliberately familiar: thumb studs for opening and a liner lock for securing the blade.
The supplied J1937-BBU (Exclusive) listing identifies this configuration with blue G10 and a black PVD-coated blade. The broader Nova platform combines a 3.45-inch AR-RPM9 blade with thumb stud deployment, a liner lock, and a ceramic ball-bearing pivot.
The Nova’s pitch is not really novelty. It is familiarity with a sharper visual identity.
The Nova is more than a tanto
The blade is where the Nova establishes its personality. CJRB specifies a 3.45-inch blade, 0.11-inch blade thickness, 7.9-inch overall length, and 4.45-inch closed length. The company identifies the blade style as a tanto, but there is more going on than the angular tip.
Designer Christian Porterfield says he repeatedly returned to a Japanese tanto shape with a harpoon element while developing the Nova. He also identifies thumb studs as his preferred opening method, which explains another prominent part of the design.
There is one specification worth treating carefully. CJRB’s Nova specification table lists the blade grind as flat, while Porterfield’s description refers to a compound grind. CJRB has also described the Nova elsewhere as having a compound flat grind.
Rather than trying to reconcile those descriptions, the safest conclusion is that CJRB’s own published material is not completely consistent about how the grind is labeled. What is not ambiguous is the design itself. The Nova is built around an angular tanto and harpoon-influenced profile rather than a conventional drop point.
Thumb studs keep things familiar
The Nova does not require you to learn an unusual opening system. It uses thumb studs, and that was not an arbitrary choice. Porterfield specifically says thumb studs are his favorite opening method.
That simplicity has practical value. Modern folding knives offer everything from flippers and blade holes to button-operated systems, but some buyers simply prefer a familiar manual interface. Thumb studs keep the Nova straightforward despite the unusual blade sitting between them.
The knife also uses a liner lock. That is a well-established folding-knife mechanism, but the specification cannot tell us how easy this particular liner is to access, how the action feels, or how satisfying the knife is to operate. Those are hands-on observations, not conclusions we can draw from a product page.
G10 and a 3.18-ounce weight make a practical pairing
The supplied J1937-BBU (Exclusive) listing identifies this version with a blue G10 handle. For the Nova platform, CJRB specifies G10 for the handle, steel for the pocket clip, and a ceramic ball-bearing pivot assembly.
The company lists the knife at 3.18 ounces, or 90 grams. That is useful context alongside the 3.45-inch blade and 7.9-inch overall length. The published specifications describe a full-size folder without an especially high listed weight.
But numbers only take us so far. They do not tell you whether the Nova will disappear in your pocket, feel perfectly balanced, or fit your hand comfortably. Pocket comfort depends on the knife’s dimensions, clip placement, your clothing, and whatever else you carry. Ergonomics depend heavily on hand size and grip.
AR-RPM9 needs context, not hype
CJRB specifies AR-RPM9 blade steel and a hardness range of 59-61 HRC for the Nova.
Those are useful specifications, but they are not performance results. A steel designation and hardness range do not tell us exactly how long a finished knife will hold an edge. Heat treatment, blade geometry, edge geometry, sharpening, what you are cutting, and how you are using the knife all contribute to real-world performance.
The same caution applies to the ceramic ball-bearing pivot. We know CJRB specifies that bearing system. Its presence alone does not prove exceptionally smooth action.
Materials and mechanisms are specifications. How well they are executed is performance.
Blue G10 and black PVD give this version personality
The supplied J1937-BBU (Exclusive) product listing identifies a blue G10 handle paired with a black PVD-coated blade.
It is a combination that suits the Nova. The blue handle separates this configuration from the familiar all-black EDC formula, while the dark blade emphasizes its angular profile.
The broader Nova family has appeared in several other G10 and blade-finish combinations, so the exact model identifier is worth checking before ordering. A photo, review, or specification for another Nova configuration should not automatically be assumed to describe J1937-BBU (Exclusive).
The tanto shape is a preference, not an automatic upgrade
The Nova’s blade is distinctive, but distinctive does not automatically mean better.
Its tanto geometry gives the knife much of its angular character and creates a very different profile from the curved belly of a conventional drop point. Which one works better for you depends on how you use a knife.
If your regular EDC jobs include opening packaging, cutting tape, trimming cord, and breaking down boxes, the relevant question is not whether a tanto is universally superior. It is whether you prefer the Nova’s geometry for those jobs.
The aggressive appearance can also encourage assumptions about piercing ability, toughness, or hard-use capability. Without testing this knife, I would not make them.
Who should buy the CJRB Nova?
The CJRB Nova makes the most sense for someone who wants familiar EDC mechanics without another familiar-looking blade.
CJRB specifies a 3.45-inch AR-RPM9 tanto blade, G10 handle, thumb stud deployment, liner lock, ceramic ball-bearing pivot, and 3.18-ounce weight for the Nova platform. The supplied J1937-BBU (Exclusive) listing adds the blue G10 and black PVD combination.
Buy it if you like thumb studs, prefer a straightforward liner lock, and want an angular tanto with a distinctive harpoon-influenced profile.
Look elsewhere if you want a very small EDC knife, strongly prefer a curved blade belly, or want a different locking mechanism.

The Nova does not need to reinvent the folding knife to stand out. It keeps the parts you already know and makes the part you see impossible to mistake for another ordinary EDC folder.
