You can't actually cut an abalone shell and make it work as a reasonable sized slab due to the curvature. What knife makers have called genuine abalone is many layers of abalone slices stacked on top of each other with any epoxy making them one solid piece. For several years they have had an ALVS (acrylic laminate veneer sheet) which is one thin veneer of abalone encased in acrylic. This is what GEC called "Looking Glass".
What we are selling as abalone on the Roundhead is actually tofu molded and colored to look like abalone.
