COPPER-TUNGSTEN

Sold out!

Denser than lead, our Copper-Tungsten toy weighs more than 35 of our 3d printed prototypes!

142 grams. The ultimate super-dense Copper Tungsten(VFG30)! 

Since it's so dense, it's a great way to build up your hand muscles for those of you more advanced.

Our Copper-Tungsten (WCu) toy is by far the densest available. Denser than silver, lead, and even mercury! We combined 30% copper with 70% tungsten for a strong and durable metal matrix that can withstand all the impacts and drops you can throw at it.

Sample density: 14.22g/cc (CW70)

Tungsten copper is very difficult to polish, but after several attempts, we made this amazing mirror finish!

PURE COPPER (99.9%+ PURE)

Sold out!

Pure copper is Oligodynamic, which means it naturally kills germs on contact. 

  • We each have about 2mg of copper in our body, without which we could not survive.
  • Along with gold, the only non-greyish pure metal 
  • Takes on its own unique hue over time and can be “reset” to brilliancy with baking soda and water (or salt and vinegar)
  • Sample density: 8.96g/cc

This is really my new favorite! Since it's oligodynamic, it will kill germs each time you use it! It's also denser than nearly any other toy out there (besides our own WCu) so it's for more advanced users or those that want to build up your hand muscles. 

Highly polished by hand! It's very satisfying to let it dance between your fingers. 

Pure Copper has the strongest known oligodynamic effect of any pure metals. It prevents growth and even kills bacteria, molds, spores, fungi, viruses and other organisms. Copper compounds have been used in medicine to treat many ailments, including arthritis. 

BLACK ZIRCONIUM

  • An exotic, rare super-metal
  • Used in jewelry and other decoration for centuries 
  • Resistance to corrosion: even higher than Titanium 
  • Named from the Persian "zargun" or gold color 
  • Common in cool stars and moon rocks 
  • Sample density: 6.52g/cc

Zirconium creates a natural, beautiful, jet-black oxide layer when heated at high temperatures. This layer makes it incredibly durable and scratch-resistant. It’s black lustrous finish is very beautiful making this the ultimate dexterity toy.

RAINBOW POLISHED TITANIUM

  • Used extensively in the aerospace industry 
  • The most biocompatible and safe metal for the human body
  • Named after Titans of Greek mythology 
  • The highest strength-to-density ratio of any element 
  • Resistance to corrosion: won’t tarnish 
  • Sample density: 4.506g/cc

It helps you train your finger dexterity passively, reduces anxiety, and keeps your mind focused. Polished finish and rainbow finish are available now!

Great piece!

This knucklebone is very well made, perfectly balanced, and has a good heft to it. I am used to lighter knucklebones but find this one conducive for some tricks that are harder to perform with lighter pieces.

I also like the rainbow finish very much, and I would recommend this piece to anyone interested in Knucklebones.

Kranite, any chance of a smaller piece in the same rainbow finish? That would be great!

I like most titanium and zirconium.

I like most titanium and zirconium. They have both a nice weight, when you're not so trained. From the look it is copper and rainbow. The colours are amazing. But I have to admit, that the black one looks classy. They look great and have a nice Feeling. Especially the rainbow titanium has a fantastic colour.
