The XS Guilloché: Mammoth & Mother of Pearl collection represents the absolute apex of the Gentleman’s Knife. These are not merely tools; they are heirloom-grade investment pieces that combine the rarest materials on Earth with the most intricate hand-detailing offered by the Gilles® Fontenille Pataud workshop in Thiers, France.

At a discreet 9 cm (3.5 inches) closed, these knives feature handles crafted from 10,000-year-old fossilized Woolly Mammoth ivory and iridescent Mother of Pearl. This exceptional luxury is matched by extensive Guilloché work—meticulous hand-chiseling that extends across the spring, the liners, and the spine of the blade. Every element is finished to a mirror polish, creating a shimmering interplay of light across the steel and organic materials.

Each masterpiece is equipped with a precision lock-back mechanism for secure use and a hardened blade stop to preserve the edge. Because fossilized ivory and natural pearl possess unique grains and color variations, every knife in this prestigious collection is individually photographed. The rare piece you select from our gallery is the exact one that will be prepared for delivery from our Jacksonville, Florida warehouse.
