Forging a Kukri from Rusty Wagon Wheel Iron: San-Mai Magic (and a Recovery!)

Ian just tackled a seriously unusual project: forging a kukri from the iron band of a rusty wagon wheel. Using a San-Mai technique and some serious improvisational skill, he turned scrap into something sharp—after a major setback, no less.

Most of us are chasing that perfect billet of 1095 or O1, dreaming of a flawless hamon. But what do you do when your raw material is… a wagon wheel? Ian just showed us what’s possible, taking a piece of rusty iron and forging it into a kukri using a San-Mai construction – a technique that blends different steels for unique properties and aesthetics. It's a reminder that bladesmithing isn't just about the steel; it's about ingenuity and problem-solving.

The project begins with a fascinating challenge: the wagon wheel's iron is “rot iron,” lacking the carbon content needed to create a functional blade. Ian’s solution? The “taco method” of San-Mai construction – an historical technique. He essentially creates a jacket of the rot iron and inserts a core of 1084 steel, which provides the necessary carbon for hardening.

If you’ve spent any time at the anvil, you know that forging can be unpredictable. Ian’s comment about the material “splitting apart” is a perfect example of that organic nature. These are the lessons you pick up in a forge class – adapting to the quirks of the metal and the heat. It’s the kind of experience you can sometimes get during a Field Trip to a bladesmithing shop, or a Live Workshop at a HolyPlace.

The Heat Treat Hiccup & The Save

Things didn’t go perfectly smooth. During the heat treat—the critical stage where the steel is hardened—the jacket and core steel separated. A lesser maker might have scrapped the project. But Ian, true to the spirit of the Rogue Blades community, saw it as a problem to be *fixed*, not a failure.

His solution? A non-traditional approach: soldering the pieces back together using flux. It's a testament to the resourcefulness that defines a truly skilled knife maker. Thinking outside the box like that is what separates the good from the great—the kind of improvisation you might see Walter Sorrells or Will Stelter pull off.

Design & Detail

Once the structural integrity was restored, Ian focused on the finer details. He added a beautiful fuller (a groove along the spine) to the blade, showcasing the unique cross-section created by the San-Mai construction. This level of detail is what separates an EDC knife from a work of art.

The attention to detail continues with the decorative “shadow line” along the edge—a subtle but striking touch that elevates the finished product. It’s the kind of refinement that a Blade Angel would appreciate, a mark of exceptional craftsmanship.

Learning from the Process

This project isn't just about forging a kukri; it's a masterclass in problem-solving and embracing the unexpected. It’s a reminder that even experienced knife makers face setbacks, and that true skill lies in the ability to adapt and overcome those challenges. If you're looking to level up your own forging skills, consider listing a custom commission—putting your skills to the test is the best way to learn.

Whether you’re a seasoned bladesmith, a budding enthusiast, or a knife collector, there’s a place for you in the Rogue Blades ecosystem. Don’t just watch – participate!

Frequently Asked Questions

San-Mai is a traditional Japanese forging technique where a core of one type of steel is encased within a jacket of another, creating a layered effect for unique properties and appearance.

The wagon wheel iron lacked sufficient carbon content to harden properly. The 1084 steel core was added to provide that necessary carbon.

Ian used a non-traditional method of soldering the jacket and core steel back together using flux, which is a risky but ultimately successful approach.
