Description
The 2407 ZRDM. Engineered Without Compromise.
The North Mountain Blade 2407-ZRDM Zirconium & Titanium Damascus Edition is a premium folding knife built for collectors and serious carry enthusiasts who demand both structural excellence and visual distinction. Every element — from the blade steel to the handle architecture — has been selected and engineered with purpose.
SLD-Magic Steel. A Blade Built to Perform.
At the heart of the 2407-ZRDM is a Tanto-ground blade crafted from SLD-Magic, a high-performance tool steel produced by Hitachi Metals in Japan. SLD-Magic is a refined evolution of D2-class steel, engineered for superior toughness, exceptional wear resistance, and outstanding edge retention. It holds a working edge through demanding use and responds well to stropping and field touch-ups — making it equally at home in a collection display or on a hard day's work.
A Handle Built Differently.
Most folding knife handles are assembled from multiple independent components. The 2407-ZRDM takes a different approach. The handle is CNC-machined from a single structural system of 7075 aluminum alloy — one of the highest-strength aluminum grades available — composed of two precisely fitted sections with an integrated backspacer built directly into the frame.
The interior is extensively hollowed to eliminate unnecessary weight without sacrificing rigidity. Fewer components mean fewer points of movement, resulting in a handle that feels solid, stable, and built to stay that way over years of use.
Titanium Damascus Inlays. Every Knife Unique.
The handle inlays are crafted from Zirconium and Titanium Damascus — a material that combines vivid, heat-developed color with the layered depth of traditional Damascus patterning. Each set of inlays displays its own naturally occurring pattern. No two 2407-ZRDM knives look exactly alike. This is not a printed finish or an applied coating — it is the material itself, shaped and revealed through the forging process.
Button Lock. Confidence On Demand.
The 2407-ZRDM deploys and locks via a precision button lock mechanism, delivering a secure, positive lockup with a clean, intuitive release. The included pocket clip is configured for tip-up carry and ships uninstalled, allowing you to set it up exactly how you carry.

Frequently Asked Questions
What makes SLD-Magic steel different from standard D2?
SLD-Magic is Hitachi Metals' advanced evolution of D2-class tool steel. It offers improved toughness and refined carbide structure compared to conventional D2, which translates to better edge stability, reduced chipping risk, and easier maintenance — especially on a Tanto grind where the secondary tip point can experience concentrated stress.
Is the Titanium Damascus finish durable or will it wear off?
The color and patterning in Titanium Damascus is not a coating or surface treatment — it is the result of the metal's natural oxide layer developed through heat. The pattern is inherent to the material itself. While the surface can develop wear over time with heavy use, the pattern does not peel or flake the way anodized or painted finishes can.
Why does the pocket clip ship uninstalled?
The clip is included and configured for tip-up carry, but ships uninstalled so you can mount it to your preferred side without any factory-installed hardware getting in the way. It takes under a minute to install with a standard screwdriver.
How does the integrated backspacer improve the knife?
Traditional backspacers are installed as separate components, which introduces an additional point of potential movement or misalignment over time. On the 2407-ZRDM, the backspacer is machined directly into the handle frame — creating a unified structural element that improves rigidity and eliminates that variable entirely.
Is this knife legal to carry in my state?
Folding knife carry laws vary by state, county, and municipality. We recommend checking your local regulations before carrying the 2407-ZRDM. As a button-lock folding knife with a 3.5-inch blade, it falls within legal carry parameters in the majority of US states, but it is your responsibility to verify local laws.
What is the MAP price and where can I purchase?
The 2407-ZRDM carries a Minimum Advertised Price (MAP) of $280. It is available through authorized North Mountain Blade dealers and directly at northmountainblade.com.
