Introduced in 2014 within the CS:GO Weapon Case collection, the Case Hardened Shadow Daggers feature a distinctive blue, gold, and silver pattern mimicking hardened steel. They became a staple among collectors and players alike.

The blades display a marbled pattern with shades of blue and gold running through a silver base, giving a rugged, industrial look. The handles are black with textured grips.

Highly coveted for their unique pattern variation, especially blue-numbered 'Blue Gem' versions, they command high market prices and are highly regarded within the community.
