Kubey Royal Liner Lock Blackout Folding Knife [KUB321X]

Colin Maisonpierre's compact window-opening folder

The Royal brings Colin Maisonpierre's shaped blade and grip to a compact folding format. A blade opening cutout and pivot-end tab give alternative deployment purchase, while the shaped handle provides a defined grip behind the short blade. Its shorter dimensions distinguish it from Kubey's larger folders.

Blade, handle and carrying size

• Blade: 2.99" (76 mm) 14C28N Sandvik stainless; black stonewash finish
• Handle: Black G10
• Mechanism: Linerlock
• Pocket size: 4.28" (109 mm) closed

Materials and cutting character

14C28N is a stainless knife steel developed around edge stability, corrosion resistance and straightforward resharpening. It is a practical choice for a knife that sees regular cutting and routine touch-ups.

The drop-point profile combines a curved cutting belly with a lowered tip, giving it a versatile outline for slicing and controlled point work.

G10 is a fiberglass-and-resin composite. Its layered construction gives the scales a durable structure, while the actual machining and surface texture determine how the grip feels in hand.

Linerlock explained

A spring section inside the handle moves behind the blade when it opens. Moving that liner aside releases the blade for folding, so the release is accessed inside the handle rather than through a separate external button.

Construction details

• Bearing pivot: Ceramic bearings support blade rotation around the pivot, adding a rolling interface to the opening action.
• Clip placement: The reversible pocket clip lets you change the carrying side. That affects pocket placement; it does not by itself change the lock-release design.
