The Bestech Cetus BT2304B is the most substantial folding knife in Bestech's titanium lineup — a full-size, hard-use folder designed by Poltergeistworks and available at Going Gear, your authorized Bestech dealer. The Cetus BT2304B pairs a 3.94-inch M390 blade finished in black PVD with horizontal satin lines with a black and bronze titanium handle inlaid with natural canvas micarta — a knife that balances premium materials, bold aesthetics, and serious cutting performance in a full-size package.
The BT2304B uses a bar lock mechanism that allows ambidextrous one-handed closing — a practical advantage over frame locks for working knife users. At 176 grams and 5.06 inches closed, the Bestech Cetus BT2304B is built for users who want a full-size, capable titanium folder rather than a compact EDC. Ceramic ball bearings, a thumb stub for multiple deployment options, and M390 steel at 60–62 HRC complete the package.
Key Features
-
M390 Blade with Black PVD + Horizontal Satin Finish — The Bestech Cetus BT2304B uses premium M390 stainless steel at 60–62 HRC, finished in a unique combination of black PVD coating and horizontal satin lines — a directional finish that gives the blade depth and visual texture while adding corrosion and wear resistance.
-
Bar Lock Mechanism — Unlike the frame locks found on most Bestech titanium folders, the BT2304B uses a bar lock — a spring-loaded bar spanning the handle that engages the blade's tang. The bar lock allows ambidextrous one-handed closing, is extremely strong under lateral stress, and is one of the most reliable locking systems in production knife making.
-
Natural Canvas Micarta Handle Inlays — The Bestech Cetus BT2304B features natural canvas micarta scales inlaid into the black and bronze titanium handle. Canvas micarta is a resin-impregnated linen composite prized for its warm organic texture, excellent wet grip, and rugged durability — a material choice that sets the BT2304B apart from carbon fiber and marble-inlay models.
-
Black + Bronze Titanium Handle — The BT2304B's two-tone black and bronze titanium handle finish creates a rich, complex aesthetic that pairs naturally with the natural canvas micarta inlays and black PVD blade.
-
3.94-Inch Blade — Longest in the Bestech Lineup — At 3.94 inches (100.1mm), the Bestech Cetus BT2304B carries the largest blade of any titanium folder in Bestech's current production range, with a 9.0-inch overall open length and serious cutting capability for demanding tasks.
-
Thumb Stub + Flipper Dual Deployment — The BT2304B offers multiple opening options: a flipper tab on ceramic ball bearings for fast one-handed deployment, plus a thumb stub for deliberate, controlled opening — giving users flexibility for any situation.
-
Designed by Poltergeistworks — The Cetus is a collaboration with Poltergeistworks, a custom knife designer known for bold, aggressive designs with strong visual presence. The BT2304B reflects their signature aesthetic: large blade, contrasting materials, and hardware that makes a statement.
-
Black PVD Titanium Clip and Backspacer — The Bestech Cetus BT2304B carries a titanium clip and backspacer both finished in black PVD, maintaining hardware consistency across the knife's all-black and bronze color story.
Who Is the Bestech Cetus BT2304B For?
The Bestech Cetus BT2304B is the right choice for three types of buyers. Working knife users who need a full-size, hard-use folder will appreciate the 3.94-inch M390 blade, robust bar lock, and canvas micarta grip — materials chosen for performance over aesthetics. Collectors and Poltergeist Works fans will want the BT2304B for its distinctive design identity: the horizontal satin blade finish, two-tone bronze/black handle, and oversized proportions make it one of the most recognizable production knives Bestech has released. And knife enthusiasts who prefer bar locks over frame locks will find the BT2304B one of the few premium titanium bar lock folders available at this price point. The Bestech Cetus BT2304B is available at Going Gear, an authorized Bestech dealer.

Frequently Asked Questions
What steel does the Bestech Cetus BT2304B use?
The Bestech Cetus BT2304B uses M390 stainless steel from Böhler, heat treated to 60–62 HRC. M390 is one of the highest-performing production blade steels available, offering exceptional edge retention, outstanding corrosion resistance, and excellent wear resistance. In the BT2304B, the M390 blade is finished in black PVD with horizontal satin lines for a unique directional texture.
What is a bar lock and how does it work on the BT2304B?
A bar lock (similar in principle to the Benchmade Axis Lock) uses a spring-loaded bar that spans the width of the handle. When the Bestech Cetus BT2304B's blade is opened, the bar snaps into a notch machined into the blade's tang, locking it open. To close, you push the bar back against spring tension with your thumb and forefinger — an action that works equally well with either hand, making the bar lock fully ambidextrous. The bar lock is exceptionally strong under lateral stress and resists accidental closure even under hard use.
What is canvas micarta and why is it used on the BT2304B?
Canvas micarta is a composite material made from layers of woven canvas fabric impregnated with phenolic resin and compressed under heat. The result is a dense, slightly textured handle material with excellent wet grip, strong impact resistance, and a warm organic appearance. On the Bestech Cetus BT2304B, natural canvas micarta inlays provide a tactile contrast to the smooth titanium frame — giving the knife a more rugged, utilitarian feel than the marble carbon fiber or Ultem scales found on other Bestech models.
What is the black PVD + horizontal satin finish on the BT2304B blade?
The Bestech Cetus BT2304B features a unique blade finish combining black PVD (Physical Vapor Deposition) coating with horizontal satin lines ground into the blade surface. The PVD provides a durable, corrosion-resistant black layer, while the horizontal satin grinding creates directional texture visible through the coating — a finish that adds visual depth and sets the BT2304B apart from solid stonewash or plain DLC blades.
How large is the Bestech Cetus BT2304B?
The Bestech Cetus BT2304B is a full-size folding knife with a 3.94-inch (100.1mm) blade, 9.0-inch (228.7mm) overall open length, and 5.06-inch (128.6mm) closed length. Weighing 176 grams, it is the largest and heaviest knife in Bestech's current titanium production lineup. Buyers who prefer compact EDC folders should consider the Bestech VK-Void BT2305D (2.85") or the Bestech Bruv BT2401C (2.95") instead.
Is the Bestech Cetus BT2304B worth the price?
Yes — the Bestech Cetus BT2304B delivers exceptional value for a full-size titanium bar lock folder with M390 steel. You get a blade steel that outperforms conventional steels at every metric, a bar lock mechanism that is ambidextrous and extremely strong, canvas micarta + titanium construction, and a Poltergeistworks design identity — all at a price point significantly below comparable custom or semi-custom knives. For users who want a serious full-size folder with premium steel, the BT2304B is a standout purchase available at Going Gear.
Bestech Cetus BT2304B vs Bestech Syn BT2306A — which should I buy?
The Bestech Cetus BT2304B and the Bestech Syn BT2306A are both premium titanium folders with ceramic bearings, but they serve very different users. The BT2304B is larger (3.94" blade, 176g), uses a bar lock, M390 black PVD horizontal satin blade, and canvas micarta handle — purpose-built for working use and bold aesthetics. The BT2306A is more refined (3.57" blade, 119g), uses a frame lock, Elmax hollow grind satin blade, and marble carbon fiber — optimized for collectors and discerning EDC users. Choose the BT2304B for a hard-use full-size folder; choose the BT2306A for a premium daily carry with elegant materials.
Who designed the Bestech Cetus?
The Bestech Cetus was designed by Poltergeistworks, a custom knife designer known for bold, aggressive folding knife designs with strong visual presence. The BT2304B reflects Poltergeistworks' signature approach: oversized proportions, contrasting materials, and a design identity that commands attention. The Cetus is one of Poltergeistworks' most recognized production collaborations.
