I held a neptunium (20.45 g/cc) sphere once. It was about the size of a baseball and I hard the hardest time lifting it. It was like lifting a full gallon jug of milk when you think it's empty - you apply a force and it doesn't budge. I had to lift it as if I was lifting a stack of books to get it off the pedestal.
Cool cube and I want one. But a metalworking friend of mine warned against getting a ring made out of tungsten. Apparently a climber had one on and broke his ring finger, and the EMTs couldn't get the ring off because the finger had swollen and they couldn't cut the ring due to the strength of the metal. They ended up having to amputate and re-attach the finger (much longer and it would have had to be amputated anywa…

Ring avulsion is pretty scary too, and can happen with any metal ring.
My dad owns both a tungsten cube and a tungsten sphere. I slightly prefer the sphere, the smoothness and lack of corners, combined with density, makes it really try to slip out of hour hand. Can be a bit dangerous for your floors, but lots of fun to hold.
Gotta say I love the ad copy for the 10 pound cube: ADD to your collection! This cube is the larger version of the world famous tungsten cube COMPARE the density to our 2.5" Aluminum cube to enhance the experience
I wonder if anyone is manufacturing tungsten dumbbells. Would be very pricy, but also super cool.

> WHY? We thought nobody would buy our 17.6lb, 3" tungsten cube. We were so, so wrong
I work sometimes in a metal shop where Tungsten alloys abound. This might be the stupidest hn post I've ever read. You bought a piece of metal at vastly inflated prices for a very narrow range of performance over a specific set of conditions. Nothing more. Being the hardest isn't being the best. Tungsten is extraordinarily brittle. A hard drop on concrete could crack it. I'd also argue without a MA (metal analysis or…
As for the value to a consumer. That comes almost entirely from its density not its hardness, something you'd know if you read OP.
As for the "vastly inflated prices" if you have the ability to produce and sell 1 kilogram cubes with the side length of an inch and a half for significantly less than OP paid then you should consider selling that information and retiring.
