The knuckles brush against the foggy holographic billboard in the shadowy alleys of Night City 🍻, and the renegade marine Lin Ye draws the matte-blue short dagger from behind his waist 🔪. The cool, nocturnal rain drenches the pristine blade, turning it into the sharpest shard of ice at the bottom of a cybernetic river 🧊; the triangular ridges on the handle fit perfectly into the grip recess of his prosthetic limb—a custom-made weapon crafted by an underground workshop using high-density polymer 3D printing 🤖.

 Corpo’s cyborg hunters close in at the alley entrance, but the metal detector scans the corner with no trace whatsoever—no one would suspect that this unassuming little blue knife is a lethal countermeasure capable of evading all detection 🔍. Lin Ye holds his breath as he lunges forward, the blade effortlessly slicing through the fiber-based bulletproof vest and precisely severing the opponent’s prosthetic power conduit 💥.

The neon lights splash across the pure blue blade, and Lin Ye wipes away the synthetic cooling fluid before turning and disappearing into the rain-soaked mist stirred up by a hovering vehicle 🌫️. This metal-free blue dagger has already taken down three Corpo pursuit teams; yet it remains hidden in the shadows, waiting for the next time it can be drawn to slash through the neon-lit night sky ⚡
