Abstract
Abstract An improved game paddle construction, utilizing a wood core and metal skin layers is provided. The wood core defines an integrated blade portion and handle portion, the blade portion of the wood core having a uniform thickness defined by opposed substantially planar surfaces. The first and second metal skin layers are respectively bonded to the opposed surfaces of the wood core to substantially sandwich the entire blade portion of the wood core therebetween. A grip is secured to the handle portion, the grip surrounding a substantial lengthwise extent of the handle portion.
