Heretic Martyr - Black Polymer Chassis - Black Tanto MagnaCut Blade - H057-4A-T

MagnaCut Button Lock with Polymer Handle

The Heretic Martyr is a modern folding knife built for everyday carry, pairing premium blade steel with a lightweight, durable chassis. It suits users who want a knife that deploys quickly and holds up to daily use without added bulk.

Blade

The 3.5" tanto blade is made from MagnaCut steel with a black finish. MagnaCut is a modern powder steel that delivers excellent edge retention, strong corrosion resistance, and better toughness than most high-hardness steels, making it a top choice for hard-use folders. The tanto shape adds strength at the tip, useful for piercing and working on tougher materials.

Handle

The handle is built from a black polymer chassis. Polymer construction keeps the knife light at just 3.88oz while remaining strong and resistant to impact. The chassis design also simplifies the internals, reducing points of failure compared to traditional liner setups.

Carry

This model uses a button lock, which secures the blade open with an internal locking bar released by pressing a button on the handle - fast to operate with one hand. The pocket clip is configurable for right or left-hand tip-up carry, making it easy to adapt to your preference.

Made in the USA.
