★ Karambit | Blue Steel (Field-Tested) is a minimalist classic from CS:GO’s earliest days, introduced with the Arms Deal update on August 14, 2013 as a rare special knife drop. This karambit uses a "Patina" finish: the blade has been cold-blued to produce a satin, blue-gray sheen with subtle violet undertones and cloudy mottling unique to the process. The curved edge and swedge catch light softly, while the textured, charcoal handle and ring keep the tactical silhouette true to the original design. Pattern index affects the density of the patina but not the overall look, ensuring a consistent steely vibe across pulls. In its Field-Tested condition, the skin shows moderate wear, with visible scratches and slight fading along the weapon’s surface.
