The Fighting Knife($165) made from fiber optic glass, by a knifemaker - Mike Cook, used a process called knapping, "a throwback method of shaping stones into useful tools, to form it". "This is what I call my Fighting Knife design. The emerald green fiber optic blade makes this knife a rather striking display piece. I enjoy picking it up, feeling it weld to my hand and watching the blade shimmer and dance in the light. "
