Heretic Knives Koschei Prototype Knife – Carbon Fiber Chassis, Hand Ground High Polish M390 Blade – Serialized – Made in USA (S/N 024)

A preview of what’s next.

The Koschei Prototype represents an early look at what may become one of Heretic’s most important upcoming releases. Built in extremely limited numbers, this prototype offers a rare opportunity to experience the design before full production begins.

This is not just another configuration. It is a development piece, refined, adjusted, and ultimately selected to move the platform forward.

And this one is individually serialized: S/N 024.

The Meaning Behind “Koschei”

The name Koschei comes from Eastern European folklore, often associated with the idea of something that cannot be easily destroyed because its essence, its “soul,” is hidden and protected elsewhere.

It is a fitting name for a knife like this.

Because the value here is not just in the materials or the finish. It is in the intention behind the design, the refinement process, and the craftsmanship that goes into shaping what this knife will eventually become.

This is where that “soul” begins.

Prototype Level Craftsmanship

Prototype pieces carry a different kind of weight.

They represent the stage where ideas become real. Where design meets function. Where adjustments are made by hand, not just by machine.

The hand ground high polish M390 blade reflects that process. Clean, deliberate, and finished with a level of attention that stands out even among high-end production knives.

Paired with a carbon fiber chassis, the result is lightweight, strong, and visually refined.

Serialized and Limited

This is not a standard release.

Prototype runs are inherently limited, and each piece carries its own place in the development of the model. The serialization marks it as part of that early story.

For collectors, that matters.

Why This One Stands Out

There are production knives, and then there are pieces that represent a moment in a maker’s evolution.

The Koschei Prototype sits firmly in the second category.

It offers a look at where Heretic is going next, while standing on its own as a finished, fully realized piece.

Supporting American Craftsmanship

Heretic continues to build their knives in the United States, focusing on materials, machining, and finishing that reflect a high standard of production.

The Koschei Prototype shows what that process looks like before the broader release.
