Green Glow - A white colour during the day and a green glow in the dark at night Kirinite® is made from a chemical process that has produced the most durable, rich and elegant grip material ever! The material is perfect for knife makers that cut shape and polish this gem like product. It's most amazing property is that the more it's polished, the more it bonds to your hands. It's not slippery, making it more desirable than ever. There's nothing like it. Please note - Material with a grain like pattern (such as MOP), may vary from being cut length ways to width ways. Material with different colours in it will have a random pattern. Some have more pattern than others.
