Aurora’s stunning mirror finish, a hallmark of this mirror polished folding knife, emerges from an intricate polishing process. The blade takes 8 hours, the handle 4 hours—over 12 hours of meticulous, micron-level craftsmanship transform it into a luxury pocket knife gleaming like art.
1. Blade Polishing: Precision at Its Peak
The M390 blade’s 8-hour polish involves four stages:
-
Rough: Hand-polished with oilstones (400, 800, 1500, 3000 grit) to remove marks.
-
Medium: Copper foil with 15-grade diamond paste, then tin foil with 8-grade, refines the surface.
-
Fine: Wool wheel with diamond paste (5 to 0.5-grade) nears a mirror finish.
-
Ultra-Fine: Wool wheel with high-gloss liquid creates a reflective sheen.

2. Handle Polishing: Smooth Elegance
The handle (steel or titanium) takes 4 hours, blending gloss and feel:
-
Rough: Sandbelts (400, 1200 grit) smooth curves and edges.
-
Medium: Copper foil with 15-grade diamond paste, then tin foil with 8-grade, enhances texture.
-
Fine: Wool wheel with diamond paste (5 to 0.5-grade) polishes to a sheen.
-
Ultra-Fine: High-gloss liquid adds a subtle, elegant glow.
