Case knife designs are pretty old-fashioned, but they’re not so old that you would describe them in geological age. Except for this custom Case Russlock with scales made from wooly mammoth tooth and trilobyte fossil.
Trilobytes lived in the ancient seas from the Lower Cambrian period hundred of millions of years ago, until the end of the Permian period. These ancient relatives of lobsters, horseshoe crabs and spiders were common for nearly 300 million years, but they went extinct 240 million years ago. They ranged in size from giants the size of manhole covers, to the minuscule fossil shown here. Their fossils are found all over the world, and as a boy I used to dig them up in the stratified shale of upstate New York.
Now some of them live on in the scales of these custom Case Russlock knives. These ultra-rare customs are among the more exclusive and expensive Cases out there, with street prices over $300 when you can find them.
If the late Stephen Jay Gould had had a pocketknife made just for him, it would have been this.
