  • Organic shell blank and method for making same
    Patent number: 6432506
    Abstract: An organic shell inlay blank is provided including a first layer of organic shell matter having two opposed surfaces defining a first thickness therebetween rendering the first layer flexible, a second layer of organic shell matter having two opposed surfaces defining a second thickness therebetween rendering the second layer flexible. One of the surfaces of the first layer substantially overlaps and is secured to one of the surfaces of the second layer. A bonding agent secures the layers together to form the inlay blank. A method for manufacturing an organic shell inlay blank is also disclosed and includes the steps of cutting a plurality of flexible pieces of organic shell matter from an organic shell, stacking the pieces in a substantially overlapping relationship with a bonding agent between the pieces, and urging the pieces together while the bonding agent cures to form the inlay blank.
