PRODUCT DETAILS
Inspired by the ethereal beauty of deep-space cosmic clouds, the KATSU Nebula (星嵐) is a masterpiece where traditional Japanese soul meets the pinnacle of modern metallurgy.
Just as a nebula is the birthplace of stars, this folding knife represents the birth of a new standard in Every Day Carry (EDC). We have fused the extreme hardness of Japanese ZDP-189 "Super Steel" with the avant-garde aesthetics of multicolored carbon fiber and aerospace-grade titanium. The result is a tool that doesn't just cut—it dominates, all while reflecting the swirling, mysterious colors of the galaxy in the palm of your hand.
The Blade: ZDP-189 Japanese Super Steel
At the heart of the Nebula lies the legendary ZDP-189 steel from Hitachi Metals. Known among blade connoisseurs as the "Holy Grail" of knife steels, it features a staggering carbon content that allows it to reach a hardness of 67 HRC.
Ultimate Edge Retention: It stays sharp exponentially longer than standard steels.
Precision Geometry: Hand-ground to a hair-splitting edge, embodying the spirit of a modern-day katana.
The Handle: Titanium & Multicolored Carbon Fiber
The handle is a study in material harmony. The frame is precision-milled from high-grade Titanium Alloy, providing a rock-solid foundation without the weight.
Inlays: We’ve integrated Imported Multicolored Carbon Fiber, offering a unique, three-dimensional visual depth. No two handles are exactly alike—your Nebula is as unique as a fingerprint.
Premium Finishes: Choose between a sleek Sandblasted finish for a refined, matte look, or our rugged Black Titanium Stonewashed finish for a dark, tactical aesthetic that hides wear and tells a story of use.
[Why the Nebula?]
Modern Japanese Aesthetics: A clean, minimalist silhouette that pays homage to traditional Japanese folding knives but is engineered for the 21st century.
Superior Ergonomics: Designed to feel like a natural extension of your hand, providing confidence in every slice.
Smooth Deployment: Tuned for a butter-smooth opening experience, ensuring the blade is ready the moment you need it.
Whether you are a professional needing a reliable edge that never quits, or a collector seeking the rarest materials in the world, the KATSU Nebula is the answer.
Available in five exclusive colorways. Choose your star.

- Keep your knife clean, particularly moving parts and locking devices.
- Keep your knife oiled; especially pivot points and the blade. Oil at least twice a year.

- Again, store your knife in a dry place.
Tips for Caring Kitchen Knives
