North Mountain Blade Jellyfish FAQ

The North Mountain Blade Jellyfish stands out for its world-class finish work and use of high-performance materials like ZDP-189 steel. These front flippers are designed for precision slicing with thin grinds and unique in-house handle composites.

What steel is used in the Jellyfish series?
The Jellyfish series features high-end steels including ZDP-189 clad steel and M390. The ZDP-189 variants are known for an extremely hard edge core and a meticulously applied hand-satin finish that remains smooth to the touch.
How does the Jellyfish blade open and lock?
Each Jellyfish utilizes a front flipper deployment with a dedicated tab that offers significant leverage for fast action. A titanium liner lock provides a secure lockup while maintaining the knife's sleek, modern profile.
What handle materials are available for the Jellyfish?
Handle options for the Jellyfish series range from G10 with silver twill inlays to exotic, in-house produced carbon fiber composites. By manufacturing their own carbon fiber, North Mountain Blade provides unique patterns and colors that are exclusive to their designs.
Is the Jellyfish suitable for daily use?
The Jellyfish is an excellent EDC choice thanks to its thin grind behind the edge and practical pocket clip. The clip is milled for durability but retains the springiness of a traditional bent clip for easier pocket carry.
Why is the North Mountain Blade Jellyfish popular?
The Jellyfish is highly regarded for its exceptional attention to detail and world-class finish work. Enthusiasts appreciate the combination of a classic silhouette with modern performance features, such as the thin blade geometry and premium handle composites.
What blade shapes are available in the Jellyfish series?
The Jellyfish series offers several distinct blade profiles, including recurve clip point, modified wharncliffe, and compound clip point shapes. Many of these designs feature a thin grind behind the edge to maximize slicing performance for daily tasks.
