Microtech Stitch RAM-LOK S/E Black Fluted Aluminum, Stonewashed M390MK Folding Knife by Borka Blades and Tony Marfione (169RL-10FL)

The Microtech Stitch RAM-LOK 169RL-10FL is a full-size folding knife featuring an M390MK blade with a stonewashed finish and a black aluminum handle with a fluted pattern. The distinctive Stitch design combines a robust silhouette with an ambidextrous RAM-LOK and manual opening via a large opening in the blade.

The 93.98 mm long, 4.00 mm thick Wharncliffe blade features a flat grind, providing a solid, functional geometry. The stonewashed finish minimizes the appearance of fine scratches, while the ball-bearing pivot and titanium tip-up clip support comfortable everyday use.

M390MK – Steel for a Massive Blade

M390MK was developed for Microtech as a highly wear-resistant variant of M390. Its excellent corrosion resistance makes it easy to maintain the knife during daily use, while its abrasion resistance ensures long-lasting sharpness. In the Stitch model, this material is paired with a solid, 4-millimeter blade cross-section.

Wharncliffe and stonewashed finish

The Wharncliffe profile provides a long cutting edge and a controlled tip, making it well-suited for both precise and heavier-duty tasks. The flat grind enhances cutting performance, and the stonewashed finish helps mask minor scratches and marks that develop during regular use.

Black Fluted Aluminum and RAM-LOK

The handle is made of black aluminum and features a fluted finish, which improves grip and facilitates stable handling of this large folding knife. RAM-LOK enables two-handed operation, and ball bearings ensure smooth blade deployment. A bead-blasted titanium backspacer and a removable titanium clip complete the design.

Technical Data

Frequently Asked Questions

What makes M390MK steel stand out?

M390MK offers high resistance to wear and corrosion, making it well-suited for a large utility folding knife. With proper care, it maintains a sharp cutting edge for a long time.

How do you sharpen a Wharncliffe blade?

For M390MK, it’s best to use diamond abrasives or a precision sharpening guide. The long, relatively straight edge makes it easier to maintain a consistent angle while sharpening.

How does RAM-LOK work?

RAM-LOK locks the blade in place using a crossbar that slides within the handle. The mechanism can be operated from either side, making it a perfect match for the ambidextrous clip and symmetrical ergonomics.

What are the benefits of the Fluted finish?

Fluted enhances the grip of the handle and improves control over a large knife. The fluted surface gives the aluminum a more technical look and reduces the feeling of the material being too smooth.

How do you care for a stonewashed blade?

The stonewashed finish effectively hides minor signs of wear, but it’s still a good idea to clean and dry the blade regularly. After more intensive use, you can wipe the surface with a soft cloth and a small amount of steel protectant.
