If I could design a knife, it would probably be a large Sebenza classic frame lock with ZDP-189 sandwiched between some stainless mosaic damascus for a blade, in Hinderer's Spanto shape (just thinner) with flipper, and a Robo Assist mechanism, ala D Ralph, and have Blue-Bark Mammoth Ivory inserts, or a meteorite cabachon insert at the rear with the Calvary carving in color anodizing.
Existing knives, would probably be A. G. Russell's exclusive William Henry GenTac with Mammoth and damascus blade.
Or a customized Microtech LCC D/A 3rd Gen with ZDP/Damascus blade and white pearl scales, with brushed Ti bolsters anodized a dark blue.
