North Mountain Blade x Lee Williams “Zen” ZDP-189 Limited edition #1 of 60
At the heart of this blade is ZDP-189, a powder metallurgy steel from Hitachi Metals. With a carbon content of 3% and chromium at 20%, it is pushed to an extraordinary hardness of HRC 65-67.
Unrivaled Edge Retention: Stays sharp significantly longer than M390 or S35VN.
San Mai Construction: The core is clad in tougher stainless steel to provide lateral strength, combining extreme hardness with practical durability.
Hand-Finished Satin: Each blade features a meticulous hand-rubbed satin finish that highlights the Tanto grind lines.
2. The Mechanism: Lee Williams' Patented Kickstop
Innovation you can feel. The Kickstop hidden flipper is one of the most sought-after designs in the custom knife world.
Clean Lines: Unlike traditional flippers, the Kickstop tab is not part of the blade. Once the knife is open, the tab disappears into the handle, leaving a sleek, snag-free profile.
Action: Paired with a ceramic ball-bearing pivot, the deployment is lightning-fast and "drop-shut" smooth.
3. The Build: Full Titanium Architecture
No compromises were made in the chassis.
TC4 Titanium Handles: CNC-machined for a perfect ergonomic grip and a sophisticated, bead-blasted look.
Titanium Hardware: The 3D-machined pocket clip and backspacer are both crafted from solid titanium.
Hidden Lanyard Loop: The backspacer features a discreet, integrated lanyard hole for those who prefer a tether without cluttering the handle's aesthetic.
