This Diamond-Encrusted Knife Is Super Sharp But Costs $150,000

Named after a venomous snake and costing a pretty $150,000, the Platinum Mamba knife might be the most bizarre yet alluring tool we’ve been charmed by since this extravagant peddle-boat or $22,000 Leica camera.

The Platinum Mamba, crafted by Sandrin Knives out of Italy, features 320 diamonds at 14.17 karats, Wyoming black jade, and tungsten carbide, a chemical compound that’s super difficult to shape into a usable blade but gives the Platinum Mamba a hardness of HRC71.

Don’t bother Googling that number — just know that tungsten carbide (the real crown jewel of the knife) is sharp as hell and holds on to that sharpness a dozen times over compared to run-of-the-mill steel.

Fun fact: Pretty much the only material that can shave down tungsten carbide is diamond. While the material is super wear-resistant, it’s also susceptible to breakage if not ground down correctly, says American Cutting Edge.

Did we mention this knife is $150,000?

Cost was apparently no concern when Rob Bianchin, founder and CEO of Cabot Guns, called up Alessandro Colombatto, director of Sandrin Knives and second-generation tungsten carbide artisan, to say (we’re paraphrasing, obviously), “Let’s make a knife nobody can buy because we can.”

We joke — the real idea was to produce a single record-breaking knife that embodied a “journey into the art and science of knife making,” says Colombatto.

“The desire to possess an object that’s as rare, beautiful, and yes, useful as the Platinum Mamba is deeply embedded in the human soul; it’s an instinct that’s existed since the dawn of man,” Colombatto continued.

The Platinum Mamba

Metallurgists at Sandrin worked with the company’s patented polyhedral tungsten carbide to draft iteration over iteration, eventually yielding what the brand is calling the hardest steel knife ever created. Then the team upped the ante by adding rare materials like the diamonds and Wyoming black jade to the handle. Because diamonds are an Italian knife maker’s best friend.

Interested parties who would really (I mean, really?) spend $150,000 on a knife as fancy as the Platinum Mamba must fill out a form online. That’s the first barrier of entry into this exuberant world of knives that cost as much as Teslas and houses.

Of course, if you’re looking for an everyday carrying knife, you could always pinch a few pennies and grab one of these champs.

The 11 best Robert De Niro movies to stream right now
From Raging Bull to The Godfather Part II, these are the roles that have defined De Niro's long career
Robert De Niro in Goodfellas

There are few actors working today who can match the career that Robert De Niro has had. Some, like Brad Pitt or even George Clooney, have been in plenty of great movies, but even they don't stack up to the kind of career that De Niro has had over the last half a century. De Niro's success can be chalked up, at least in part, to his collaboration with great directors. De Niro has been in some of Martin Scorsese's best movies, and Scorsese isn't the only director who knows how to use him.

Really, though, it's De Niro himself who deserves a lot of the credit. Although he's been in plenty of schlock, the best movies of his career are up there with the best movies ever made. When he emerged on the scene, De Niro showed off his ability to play a range of different types, and his skills have only deepened as the years have gone by. Keep reading and find out what Robert De Niro movies you cannot miss if you have already.

The 12 best Adam Sandler movies (they’re not all comedies)
From Uncut Gems to Happy Gilmore, these are the films that defined Sandler's career to date

What is there left to say about Adam Sandler? The Sand-Man has been a fixture of pop culture for well over 20 years, having worked first on Saturday Night Live and then broken out in a series of farcical, wonderful comedies in the years after his departure. He's one of the biggest comedy stars on the planet, and he's been part of some of the best comedy movies. He's also made plenty of movies that nobody should be forced to watch twice.
For every movie that has immediately been relegated to the trash bin of history, though, Sandler has also made an indelible comedy or a surprising turn into drama. While he could have emerged looking a little bit like a one-trick pony who relies on funny voices for cheap laughs, Sandler turned out to be far more complicated than that. He is a genuinely great actor whenever he wants to be. The rest of the time, he's content to make silly movies with his best friends. Here are the best Adam Sandler movies you need to watch now.
