Highly anticipated. Finally here. Built to move.

The Heretic NYX has been one of the most talked-about OTF releases in recent memory, and for good reason. This version features the tanto blade in a 2-tone black tactical finish with all black hardware, giving it a clean, aggressive look on a platform designed for real everyday carry.

This is one of the easiest ways to step into a premium USA-made OTF, without jumping into the higher price tiers.

Built for Real EDC

The NYX was designed with a slim profile and strong blade-to-handle ratio, making it one of the more practical OTF options in this size range. 

• Slim in pocket

• Full-size cutting performance

• Balanced feel in hand

It carries easy, but doesn’t feel small when you use it.

Tanto, Done Right

This version runs the tanto blade, giving you:

• Reinforced tip strength

• Straight edge control for precise cuts

• Aggressive, tactical profile

Paired with the 2-tone black finish, it leans fully into that modern tactical look.

MagnaCut Performance

CPM MagnaCut brings a balanced, real-world performance package:

• Strong edge retention

• Excellent corrosion resistance

• Toughness that holds up under use

It’s one of the best all-around steels being used today, and it fits this knife perfectly.

Double Action OTF

The NYX uses a double action OTF system:

• Push forward to deploy

• Pull back to retract

• Fast, consistent, and satisfying

The stepped button is crisp and responsive, built for repeated use. 

Clean, Tactical Build

This configuration keeps everything dialed in:

• 2-tone black blade for contrast and depth

• All black hardware for a unified look

• Black aluminum handle that keeps weight down

It’s aggressive without being overdone.

Made in the USA

Heretic builds the NYX in-house in the USA, with tight machining and attention to detail throughout. 

Why This One Stands Out

The NYX hits a sweet spot.

You’re getting MagnaCut, a proven OTF platform, and a clean tactical configuration, all at a price point that makes sense for someone stepping into premium automatics.

This is exactly the kind of knife that doesn’t sit long once it lands
