Gradient color

This is a specially designed flailing knife, also known as a butterfly knife. Its defining characteristic is its blade, which swings freely like a fan, allowing it to kill without a trace. For this reason, butterfly knives are banned in many countries. This weapon is chrome-clad, airbrushed with a gradient, transparent finish. It's more than just a weapon; it's a trend. - Imogen, an Intern Arms Dealer
