Pete Gray (Gray Precision) certainly has created his own unique and recognizable style that many have come to desire. Whether it's his knives, lanterns, spinning tops or thumb disks, you can guarantee the piece you receive will have beautiful attention to detail and precision work. Each piece is crafted by hand on a manual lathe in his Medford, OR shop. He uses modern materials such as Zirconium and Titanium, which have both a quality and cool factor. We are truly pleased to be offering varying products from Pete. Turboglow is a light charged glow in the dark material. It is a composite material and while it is strong, it is NOT as strong as metal. It IS breakable. If you throw this on your keys and sit on it,shut it in the car door, or abuse it, it WILL break!
