EIKONIC Aperture Liner Lock Black Folding Knife [EKC550BB]

An opening window within an angular folding outline

The Aperture integrates an elongated opening window into the blade, alongside a pivot-end tab. These offer different places to gain purchase when deploying the blade. The cutout continues the angular geometry of the handle, making it a functional detail as well as part of the design's appearance.

A liner lock supports the working blade and a separate clip supplies pocket attachment. The textured scales are offered in materially different configurations, including G10 and canvas micarta.

Blade, handle and carrying size

• Blade: 3.13" D2 tool steel; black PVD coated
• Handle: Black G10
• Mechanism: Linerlock
• Pocket size: 4" (10.16cm) closed

Materials and cutting character

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.

After cutting, clean and dry the blade before storage. A light protective oil is particularly useful for this steel when the knife will be exposed to moisture or left unused for a while.

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.
