Marfione Custom Atreus Double Edge OTF with DLC Cracked Ice M390MK Blade and Purple Haze Titanium Inlays

The Marfione Custom Atreus is a high-end custom OTF from Marfione Custom Knives featuring the new Zero Blade Tolerance platform, a 4″ M390MK double-edge blade, DLC Cracked Ice finish, black aluminum handle, carbon fiber inlays, Purple Haze titanium inlays, DLC Hard Cut hardware and accents, a milled titanium pocket clip with ceramic ball, and the new titanium glass breaker.

This Atreus has the elevated custom presentation collectors expect from Marfione Custom Knives, but the performance story is just as strong. The updated OTF drive system is designed for an extremely smooth, easy open-and-close cycle. The new switch rides on a milled platform, which helps break up pocket lint and debris while reducing friction. That design helps improve reliability and can lower the frequency of cleanings compared with older OTF systems.

Marfione Custom Atreus with Zero Blade Tolerance

The Marfione Custom Atreus is built around a 4″ double-edge M390MK blade with a 3.6″ cutting edge. The DLC Cracked Ice finish gives the blade a dark, high-contrast custom look, while the double-edge profile reinforces the Atreus as a serious Marfione OTF. The blade presentation is aggressive, clean, and distinctly premium.

The handle uses premium aircraft aluminum with carbon fiber and Purple Haze titanium inlays. The purple inlay work adds a vivid custom accent against the dark handle and carbon fiber, while the screwless handle design keeps the presentation clean from end to end. The milled titanium pocket clip, ceramic ball, DLC Hard Cut hardware, and titanium glass breaker complete the build with details that feel deliberate and collector-grade.

Marfione Custom Knives Collector Appeal

Marfione Custom Knives represents the custom and limited-production side of the Microtech family. These knives appeal to collectors because they combine Microtech’s tactical OTF design language with custom-level materials, special finishes, refined presentation, and limited availability. This Atreus fits that formula well with its M390MK double-edge blade, DLC Cracked Ice finish, carbon fiber, Purple Haze titanium inlays, new drive system, and complete Marfione Custom presentation.
