Materials

Every material.
Chosen deliberately.
Every time.

Not for spec-sheet appeal or trend-chasing, but because it performs the way we need it to in the conditions our knives are actually used in. This page exists to give you a straight answer on what goes into our blades and why those choices matter.

Steel

Steel is the foundation of the knife. Everything else builds from it.

We primarily use AEB-L and Magnacut across our main line.  These two steels that have proven themselves through performance, not trends. Each is selected for how it behaves in real use: edge stability, toughness, corrosion resistance, and ease of maintenance.

For custom builds, we can work with a wide range of steels based on your specific needs and preferences.

AEB-L

AEB-L was originally developed for razor blades, where fine edge performance and consistency matter most. That origin shows in how it performs in a knife.

It takes a very fine, clean edge and holds it well without becoming brittle. It’s tough, stable, and forgiving in use making it an excellent choice for both everyday carry and kitchen work. It also sharpens easily, which matters over the life of the knife.

AEB-L isn’t flashy, but it performs. That’s why we use it.

Magnacut

Magnacut is a newer steel designed specifically to solve the trade-offs that have always existed in knife steels balancing edge retention, toughness, and corrosion resistance without sacrificing one for the other.

Developed using modern metallurgy, it offers excellent corrosion resistance with high toughness and strong edge retention. It performs well in harsh environments and holds up under hard use without chipping or failing.

Magnacut is a high-performance steel that delivers across the board, making it a strong choice for field, hunting, and all-around use.

Custom Steel Options

For custom builds, we can work with a variety of steels beyond our standard offerings.

If you have a specific steel in mind, we’ll match it with the right heat treat and build approach to ensure it performs the way it should

The right steel matters. How it’s treated matters more.

Heat Treating

Heat treating is what brings steel to life.

The same steel can perform very differently depending on how it’s treated. Hardness, toughness, edge stability none of it is guaranteed out of the box.

The Process

Every steel we use whether AEB-L, Magnacut, or custom selections is paired with a heat treat process specific to that steel. Not a generic recipe.

We’ve spent years refining our cycles through testing, adjustment, and real-world use. What we run today is the result of that work, not guesswork or off-the-shelf recommendations.

The goal is simple: a blade that holds an edge, resists chipping, and performs consistently under load.

Steel-Specific Approach

Different steels require different treatment to reach their full potential.

  • AEB-L is treated to maximize edge stability and toughness while maintaining a fine, clean edge.
  • Magnacut is dialed to balance corrosion resistance, toughness, and edge retention without pushing the steel into brittleness.

Each batch is controlled, repeatable, and built around how the knife will actually be used, not just lab numbers.

Hardness (HRC)

Hardness is one of the measurable outcomes of heat treating, and it’s commonly expressed as HRC, or Rockwell Hardness (C scale).

The Rockwell test dates back to the early 1900s and was developed as a consistent way to measure how resistant a material is to indentation. In simple terms, it tells you how hard the steel surface is.

For knives, hardness matters but only in balance.

  • Higher hardness can improve edge retention
  • Lower hardness can improve toughness and resistance to chipping

We don’t chase extreme numbers. We target hardness ranges that match how the knife will actually be used, balancing edge life with durability and reliability.

Why It Matters

A knife isn’t defined by steel alone.

Two blades made from the same steel can perform completely differently depending on how they’re heat treated.

We treat every blade with that in mind so performance in the field matches what the steel is capable of delivering.

Steel sets the potential. Heat treat delivers it.

Handle Materials

Handle material matters as much as the blade.

It affects grip, control, durability, and how the knife feels in hand over time. We choose materials that perform in real conditions not just look good on a shelf.

Richlite

Across our main line, we use Richlite in a range of color options, selected for consistency, durability, and performance in the field and kitchen.

Richlite is a composite material made from layers of paper infused with resin and compressed under heat and pressure. It was originally developed in the early 20th century as an industrial material, valued for its strength, stability, and resistance to moisture.

Over time, it found its way into demanding applications from aerospace and tooling to high-end architectural surfaces because it performs where natural materials can fall short.

In a knife handle, those same qualities matter:

  • Stable in all environments – won’t swell, crack, or shift with moisture or temperature
  • Durable under use – resists wear, impact, and long-term breakdown
  • Consistent grip – maintains traction without becoming overly aggressive
  • Low maintenance – no special care required

Richlite also develops a natural character over time, taking on subtle wear that reflects use without compromising performance.

Why We Use It

We chose Richlite because it works.

It delivers the durability of a modern material with a feel that’s closer to natural handle materials. It holds up in wet conditions, cleans easily, and stays consistent from one knife to the next.

Available in multiple color options, it allows us to offer variation without sacrificing performance.

Built to be used. Built to last.

Surface Protection

The finish on a blade isn’t just visual, it plays a role in how the knife performs over time.

Every knife we produce is finished to a refined working surface that balances corrosion resistance, durability, and ease of maintenance. The goal is a clean, consistent finish that holds up to real use without requiring special care.

Working Finish

It’s not about making a knife look perfect on day one.
It’s about how it looks and performs after it’s been used.

Our standard finish is designed to reduce surface friction, resist corrosion, and maintain a clean appearance through regular use.

Over time, light marks and wear will develop. That’s expected. Those marks are part of the knife’s story and do not affect performance.

A blade that shows use is a blade doing its job.

Coatings & Custom Finishes

As we continue to expand our line, we will offer additional finishes and coatings where they add real value.

This includes options like Cerakote, a polymer-ceramic coating known for its corrosion resistance, chemical resistance, and surface durability. It’s widely used in demanding environments for a reason.

We apply coatings selectively only where added protection makes practical sense, such as in high-moisture or hard-use environments.

Custom builds and future releases will include a range of finish options based on intended use and customer preference.

What to Expect

All finishes will wear over time with use. That wear is cosmetic only.

It does not affect edge geometry, structural integrity, or performance.

We design our finishes to age honestly so the knife reflects how it’s been used, not just how it looked when it was new.

A clean finish matters. How it holds up matters more.

Materials matter. Execution matters more.
