Why it works

Bright Water marbles blue into white down the blade, and Sport Gloves Amphibious use the same two colours in a crackled finish. Both items read as water on stone, one polished and one matte. The butterfly is the knife people buy for the inspect animation, so it is worth the wear that shows the blade cleanest.

What it costs

With Butterfly Knife | Bright Water in Minimal Wear and Sport Gloves | Amphibious in Field-Tested, the set comes to $844. Butterfly Knife | Bright Water is 67% of that; in Field-Tested it is $516, which saves $46 and is hard to spot in first person.
