This 2006 Case XX Muskrat began life as a Pocket Worn 10th Anniversary edition (1996–2006), with the commemorative etch still visible on the master blade.

Historical Note
Fossilized mammoth tooth, mined from ancient permafrost in Siberia, Alaska, and Canada, is between 10,000–30,000 years old. Mineralization over millennia creates its unique reds, blues, and earthy tones, each slab truly one-of-a-kind. Because the raw material is brittle, it is carefully stabilized and polished before being shaped into knife scales, making knives like this both a technical and artistic achievement.

The mammoth tooth re-handle work on this Case Muskrat was likely performed by a custom shop such as Michael Prater’s Painted Pony Designs or another craftsman working in the same tradition. These customizers were well known in the mid-2000s for elevating Case XX knives with exotic materials, filework, and high-polish finishes, creating unique collector-grade pieces from standard Case patterns.

Collector’s Note
This knife represents the meeting of American knife-making heritage and custom artistry. As a base, it is a 2006 Case XX Pocket Worn 10th Anniversary Muskrat—a collectible in its own right. Enhanced with ancient mammoth tooth scales and custom detailing, it becomes a luxury collectible that appeals to both Case enthusiasts and lovers of unique handle materials.

Custom mammoth tooth Case knives are increasingly sought after, and mint examples like this are not only visually striking but also historically significant—linking modern craftsmanship with prehistoric natural history.
