We’ve covered, tested and put quite a few gorgeous pocket knives over the years. We even put together an entire piece about the best expensive pocket knives out there. None of those options compare to Sandrin Knives and Cabot Guns collaboration, The Platinum Mamba knife. Inspired by groundbreaking achievements from both the worlds of motoring and watchmaking, The Platinum Mamba combines the very best the world has to offer in terms of luxury and quality. We’re talking luxury the likes of which the world has only seen in historic pieces like The Crown Jewels and Faberge eggs. 14.17 Karats from 320 diamonds. 11.5 ounces of platinum. Wyoming Black Jade. A Tungsten Carbide blade. The finished product is the result of a two-year quest that involved fifty of the world’s most skilled and talented artisans that helped create a knife with a $150,000 price tag that might be the most expensive (and beautiful) knife ever created.
