Blacked Out by Day. Electric by Night.

The Heretic Medusa just stepped into another dimension.

The brand-new Secret Cel Shade finish is unlike anything else in the knife world right now. In normal light, the Medusa keeps its dark, tactical presence. Clean. Stealthy. Purpose-built. But hit it with UV light and the Cel Shade finish ignites, revealing bold outlined accents that completely transform the blade and handle.

It is part tactical tool, part graphic novel energy.

This is not subtle. It is intentional.

What Is Secret Cel Shade?

Cel shading is inspired by animation and graphic art techniques, where bold outlines and contrasting edges give objects a stylized, almost 3D illustrated appearance. Heretic took that concept and engineered it into a working automatic knife finish.

Under UV light, the blade lines glow and pop, giving the Medusa an entirely different personality. It is two knives in one.

By day: blackout tactical.

By night: head-turning showpiece.

Built on the Proven Medusa Platform

The Medusa is already one of Heretic’s most respected automatic folders. Designed for hard use, it delivers fast, authoritative deployment and solid lockup every time.

This version keeps all the performance the Medusa is known for, but adds a finish that sets it apart from anything else in your collection.

Note from Lone Star Knife & Supply

Every once in a while something comes along that reminds you this industry can still surprise you. The Secret Cel Shade Medusa is one of those knives. It respects the hard-use roots of the platform, but isn’t afraid to have some fun.

If you want something tactical that can also steal the show when the lights go down, this is it.

Crafted for chaos. Built to glow.
