Why it works

Ruby gives the blade a deep translucent red with no pattern to distract from it, and the gloves marble red, blue and gold across pale leather. The gloves carry a second colour the knife does not have, which stops the set from being a single block of red.

What it costs

With M9 Bayonet | Doppler (Ruby) in Factory New and Specialist Gloves | Marble Fade in Minimal Wear, the set comes to $10,204. M9 Bayonet | Doppler (Ruby) is 96% of that; in Factory New it is $906, which saves $8,920 and is hard to spot in first person.
