Case XX Classic Ultra Rare Mammoth Fossil Prototype Cheetah Pocket Knife

Description The case mastodon fossil prototype cheetah pocket knife is a significant piece of cutlery history, representing a rare glimpse into the development of the Case Classic series. This ultra-rare prototype features handles crafted from genuine 20,000-year-old mastodon fossil mined from the Siberian permafrost. The material displays a natural patina and characteristic aging that can only be found in prehistoric ivory. As is typical with this ancient material, small, natural stress lines are visible around the pins, adding to the authentic character of this specific historical specimen. This early 1990s prototype is distinguished by its unique factory markings, including “Prototype” etched onto the back of the main blade alongside “Mastodon Ivory” lettering. The knife is built on the large Cheetah frame with a swing guard and a stainless steel clip blade. While the blade clicks firmly into the open position, it is important to note that as a prototype, it does not completely lock, which is a common characteristic of development pieces from this era. Every aspect of this knife serves as a testament to the experimental craftsmanship of the W.R. Case and Sons history. Owning a case mastodon fossil prototype cheetah pocket knife offers a rare opportunity to possess a one-of-a-kind artifact that was never intended for general retail production. Its status as a prototype makes it a top-tier investment for serious collectors who specialize in Case Classics or rare handle materials. This knife comes in a replacement black felt jewel box and remains in its original, unsharpened condition. Secure this case mastodon fossil prototype cheetah pocket knife to serve as the crown jewel of your collection.
