The atlas in the background is a reproduction of a 1698 atlas by a fellow named Frederick De Wit. He might be a very distant forefather of Dirk de Wit, who, you guessed it, made the 2 knives. The top one he calls his "revalidation" knife, and is part of a series which was made after Dirk got struck by disease. Damasteel blade, brass handle, micarta scales. The bottom one is a knife that Dirk built on my request. Damasteel blade, mammoth ivory inlays. Fit and finish on both knives are second to none. Dirk is one of the greatest folding knife makers in my opinion.
