Bestech Knives Cetus Knife: Masterclass in M390 Steel and Innovative Design

High-quality, Ergonomic, Precise, Versatile, Durable

The Bestech Knives Cetus, the offspring of the cosmic and artistic forces of Poltergeist Works. At a glance, these knives look like raw power and elegance have had a chance meeting. They represent the beautiful coexistence of utility and design, in an unlikely world of cutlery and art.

The blade, at a thickness of 0.15″, is a manifestation of strength and precision. It's crafted from M390 material, a high-quality steel characterized by its edge retention, corrosion resistance, and overall toughness. The blade is just shy of 4 inches – a generous length that strikes a balance between practicality and portability.

The handle incorporates a titanium frame with varying inlays – carbon fiber and two types of Micarta. The marriage of these materials not only confers an impressive strength-to-weight ratio but also lends an air of sophistication to the overall design. The sleek silhouette coupled with the durability of these materials makes these knives a joy to hold and behold.

Each knife is 9 inches in length and weighs in at a hefty but not unwieldy 185g or 176g, depending on the inlay. There's an undeniable sense of substance when you hold these knives. They are solid, but far from cumbersome.

The hardness of the blade, 59-61HRC, underlines its durability. For the uninitiated, the Rockwell scale measures the hardness of a material, and in this context, a higher number often signifies a knife that will retain its sharpness even under heavy use.

What's truly interesting about these knives, however, is their designer – Poltergeist Works. A design studio renowned for its unique and functional creations, it's left an undeniable stamp on these knives. They bear the same distinct styling and philosophy that has won Poltergeist Works fans worldwide.

In summary, these knives are the embodiment of sophistication, utility, and durability. They represent a meeting point of sorts – a juncture where aesthetic allure and functional demands align. Whether you're an enthusiast or a casual user, the Bestech Knives Cetus models offer something to appreciate.


  1. High-quality Materials: The Cetus knives utilize M390 steel for the blade, known for its excellent edge retention, corrosion resistance, and durability. The handle materials, which include titanium with carbon fiber or Micarta inlays, add a touch of class and robustness.
  2. Robust Design: Created by Poltergeist Works, these knives display a perfect blend of aesthetics and function. The design feels sturdy and reliable with rock-solid lockup, ensuring the safety of users.
  3. Ergonomics: The handle is slightly contoured, providing a comfortable and secure grip. Its unique shape enables forward-leaning cuts with enhanced control.
  4. Cutting Capability: The blade features a drop point Tanto design with a super-thin hollow grind, facilitating precise and efficient cuts. Its design allows for versatile use – from robust tasks to detailed precision work.
  5. Excellent Action: Despite the use of a thumb disc, which can be hit or miss, the Cetus has smooth action and an easily accessible crossbar lock. The thumb disc is textured, providing an adequate grip for deployment.
  6. Great Fit and Finish: The knife's build quality is impressive, with perfect centering and excellent blade to handle ratio. The high-quality Micarta and titanium finishing are noteworthy.
  7. Effective Clip Design: The clip is tall and accommodates even thick jeans with ease. It offers a smooth and deep carry, adding to the overall convenience of the knife.


  1. Potential for Blade Coating to Wear: The blade has a coating that might wear off with extensive use. This is not a defect but a characteristic of coated blades.
  2. Sharpening Challenges: Due to its Tanto design, you'll need to treat the main edge and the tip as separate edges during sharpening or stropping.
  3. Thumb Disc Learning Curve: Users may take some time to get accustomed to the thumb disc's positioning and deployment.
  4. M390 Hardness: Although the knife uses high-quality M390 steel, its hardness rating of 59-61HRC could be slightly improved to fully exploit the steel's potential. A hardness of over 61 would be ideal.
  5. Detent: The detent is on the lighter side, which some users may not prefer, though it's not necessarily a con due to the type of deployment it uses.
