How Our Knives Are Made

High-temperature forging

Forged Under Intense Heat

We start with premium high-carbon steel, heated to extreme temperatures and repeatedly forged by hand. This traditional process refines the blade structure, increases density, and builds a rock-solid foundation for lasting performance in any outdoor condition.

High-quality Knife

recision-Honed & Field-Tested

Every blade is ground and sharpened to a razor edge with a fine 15° bevel. But we don’t stop there—each knife is stress-tested using real-world simulations, ensuring excellent sharpness, edge retention, and resistance to breakage under pressure.

Damascus Blades

Crafted with 67-Layer Damascus Steel

At the core is ultra-durable AUS-10 steel, surrounded by 66 alternating layers of stainless steel to form a beautiful and tough Damascus pattern. This multilayer build provides high hardness, rust resistance, and just the right amount of flexibility for demanding outdoor use.

Q&A

Let's explore what makes this knife unique!

What makes Koroboshi outdoor knives different from traditional outdoor knives?

Koroboshi knives are not built to be the most tactical or heavy-duty survival tools. Instead, we focus on aesthetic design, uniqueness, collectibility, and everyday utility. They're perfect for light camping tasks, EDC (everyday carry), and those who appreciate finely crafted gear with a personal touch.

Are your knives made from real Damascus steel?

Yes. Our Damascus knives are made using true layered steel techniques, featuring a unique wave pattern that is both visually stunning and functionally strong. Each blade is forged with care, making every knife one of a kind.

Can I use Koroboshi knives for outdoor cooking?

Absolutely! Our knives are designed with versatility in mind, and they’re great for tasks like slicing fruit, prepping ingredients by the fire, or cutting small items when camping or hiking.

Is the knife more of a display piece or a practical tool?

Both. While Koroboshi knives are collector-worthy due to their distinct design, they are also fully functional. Whether you're using them or displaying them, they are built to delight both hands and eyes.

Are your knives legal to carry in the U.S.?

Knife laws vary by state and city. Most of our knives fall within legal everyday carry (EDC) standards, but we recommend checking your local laws regarding blade length and carry regulations before taking it out with you.
