INTRODUCING

THE ONYX SERIES.

ONYX Series 8 inch chef knife with its boxONYX Series 8 inch chef knife with its box

INTRODUCING

THE ONYX SERIES.

A world first. ONYX is the first knife collection built around carbon fiber, the material cars have relied on for years when only perfection and lightness will do. We are bringing that same standard to knives.

It gives every ONYX a slick blacked-out look you will not find on any other knife in the world, and a handle that weighs almost nothing in your hand.

Under it, the best steel we could source: a hardness that stays, an edge that lasts for years, sharpened by hand before it ships and guaranteed for life.

THE ONYX 8" CHEF KNIFE

Doesn't Have To Look Like Every Other One.

Most kitchen knives follow the same formula: silver blade, wooden handle, familiar silhouette. ONYX takes that format somewhere darker, with blacked-out steel and a forged carbon fiber handle no other knife has. Tap a number to see what changed.

The best steel we could source, under a black finish. A hardness that stays, so the edge lasts for years, and a look no polished blade will ever have.

Layers of carbon fiber pressed into resin. Featherlight, stiffer than any wood, and marbled so no two knives match.

The shape you already trust. Long strokes through a roast, a tip that still tucks in for fine work.

The steel runs the whole length of the handle and is pinned through it. One piece, for life.

FULL TANG, RIVETED

Made To Work Together.

The steel runs the whole length of the handle and the carbon fiber scales are pinned straight through it. One piece, for life.

8" blade. Forged carbon fiber. Blacked-out steel.

FULL TANG, RIVETED
ONE KNIFE.

FOUR WAYS TO WORK.

SLICE

SLICE

Long, clean strokes through a steak or a roast, in one pass.

CHOP

CHOP

Herbs, greens, asparagus. The full length of the blade, rocking on the board.

DICE

DICE

Onions, shallots, garlic. Small, repeatable cuts with the tip.

CARVE

CARVE

The reach to take a whole roast bird apart in a few strokes.

A DARKER TAKE ON THE CLASSIC CHEF KNIFE

The Onyx Series began with a simple thought: why should a chef knife have to look like every other chef knife?

The kitchen is full of familiar forms. Polished steel. Warm wood. The same silhouettes passed from one generation to the next. We wanted to take one of the most recognizable tools in the kitchen and look at it differently.

Made for the cook. Created to stand apart.

QUESTIONS, ANSWERED

BEFORE YOU ASK.

The things people want to know before they order.

The shape is the classic 8" chef profile you already know how to use. What changes is everything you see: high-carbon stainless steel blacked out from tip to tang, and a forged carbon fiber handle. One dark silhouette that cuts like a chef knife and looks like nothing else on the board.

Slicing, chopping, dicing, and carving. Herbs, onions, potatoes, a whole roast chicken, a rack of ribs. It is the one knife that handles most of a meal on its own.

No. 8 inches is the size most cooks settle on once they have tried shorter ones. It gives you longer strokes through big ingredients and still tucks in for fine work near the heel.

The black finish is bonded to high-carbon stainless steel and built for daily use. Wash it by hand, dry it, and it keeps its look. Light marks along the edge over years of cutting are normal and do not affect how it cuts.

It arrives razor sharp and holds that edge through months of normal cooking. When the day comes, a few passes on a sharpener bring it right back.

Forged carbon fiber: carbon strands pressed into resin under heat and pressure. Featherlight, stiffer than any wood, it does not soak up water or crack, and no two handles carry exactly the same marbled pattern.

No. Dishwashers damage any knife worth owning. Hand wash with warm water, dry it, and put it away. Thirty seconds.

Not included. The leather sheath in our store fits it and protects the edge in a drawer or a bag.

Orders leave our warehouse within 1 business day. Delivery takes 3 to 5 business days anywhere in the US, and there is a 2-Day option at checkout if the wait feels long.

Cook with it for 30 days. If it is not the knife we promised, write to support and you get a full refund. Every ONYX is also guaranteed for life.
