Ocaso Knives OTF Auto Lucent Large Green Diamond Handle M390 Harpoon Blade 18LLG

The Ocaso Knives OTF Auto Lucent Large Green Diamond Handle M390 Harpoon Blade is a modern out-the-front automatic built for smooth performance, refined carry, and everyday confidence. Designed to balance clean aesthetics with serious materials, this knife delivers fast, reliable deployment in a slim profile that disappears in the pocket until it’s called into action.

At the heart of the Lucent Large is a 3.5-inch harpoon-style blade crafted from premium Böhler M390 steel. Known for exceptional edge retention, corrosion resistance, and overall toughness, M390 is a top-tier steel choice for users who expect consistent performance. The satin finish enhances the blade’s clean look while highlighting the distinctive harpoon profile, giving it both visual impact and functional strength. With a blade thickness of just 1.2mm and a hardness rating of 59–61 HRC, it slices efficiently while maintaining durability.

The dual-action out-the-front mechanism provides quick, effortless deployment and retraction with a smooth, controlled feel. Jimping along the top and underside of the handle improves traction during operation, helping maintain control when activating the blade. This thoughtful attention to ergonomics makes the Lucent intuitive and comfortable to use.

The handle is machined from lightweight 6061-T6 aluminum and finished in a striking green anodization with an elegant diamond-pattern cross-hatch texture. This pattern not only elevates the knife’s appearance but also enhances grip security without adding bulk. At just 2.2 ounces, the Large Lucent offers full-sized capability in an exceptionally light package, measuring 7.9 inches overall.

An ambidextrous deep-carry pocket clip wraps cleanly around the handle, keeping the knife discreet and streamlined in-pocket. Despite being an OTF automatic, it maintains a modest, unassuming look that fits naturally into daily carry.

Designed by custom knifemaker Andrew Demko, the Lucent reflects a focus on mechanical reliability, efficient design, and modern styling. Precision-made parts by Bestech and final assembly in California ensure consistent quality backed by thoughtful engineering from Ocaso Knives.

The satin M390 harpoon blade and green anodized aluminum handle make the Lucent Large a standout OTF that’s light, fast, and refined without sacrificing performance, available at SMKW.
