Why it works

Heat Treated tints the Five-SeveN slide through blue and gold the way tempered steel does, and Hydra Gloves Case Hardened carry the same blue with gold studs along the edge. Both finishes imitate metal reacting to heat, so they are describing the same idea on two different items. Case Hardened patterns vary between copies, so the blue to gold ratio is worth checking on the listing.

What it costs

With Five-SeveN | Heat Treated in Factory New and Hydra Gloves | Case Hardened in Field-Tested, the set comes to $73. Hydra Gloves | Case Hardened is 80% of that, so it is the piece to budget around.
