More into "Aquaman" than "The Green Lantern"? Then this is the one for you! Aqua Hyperglow glows with a very nice blue color. More "blue" than aqua/green, but not a dark blue, in the day it is a Green/Aqua color.. It really is very striking. Radius style LBS button made from the high performance glow in the dark acrylic composite product: "Hyperglow". These are charged by light and continue to visibly glow for hours. Fits all Strider knives and many other knives that take the 3/8" diameter "Hinderer Lockbar Stabilizer" button.
