About the WE Knife Flight Line

The WE Knife Flight Line series pairs an aerodynamic titanium handle with a premium M390 clip point blade and a nested liner lock mechanism. Available in multiple finishes, this limited edition series offers exceptional precision engineering for collectors and everyday carry enthusiasts.

What blade steel does the WE Knife Flight Line use?
The WE Knife Flight Line features high-performance M390 stainless steel, prized for its excellent edge retention and corrosion resistance. The 3.81-inch clip point blade is available in stonewashed, black stonewashed, or hand-rubbed satin finishes.
What lock mechanism is used on the Flight Line series?
The Flight Line series uses a nested liner lock rather than a traditional frame lock. This design delivers secure blade lockup while maintaining clean, smooth titanium handle scales on the exterior.
What are the key design features of the WE Flight Line?
Each Flight Line folder features machined titanium handles with faceted interior detailing, a pocket clip anchored by a single barrel post, and a specialized backspacer with an integrated lanyard pass-through. The knife opens smoothly via a subtle flipper tab.
Is the WE Flight Line a limited edition knife?
Yes, the WE Knife Flight Line is a serialized limited production run. Each knife features individual numbering etched directly onto the build.
Why is M390 steel popular for folding knives?
M390 is a premium powder metallurgy steel known for high wear resistance and corrosion resistance. It holds a sharp edge through extended cutting tasks, making it ideal for daily carry and heavy-duty utility knives.
