Description

Graphene (High Purity) Ice Knife - 100 mm x 25 mm x 1.2 mm - 6.7 GramsPure Graphene (aka "Pyrolytic Graphite"). This piece is the perfect size and shape to be used as an Ice "Knife". We think this product is amazing. Touch it to a piece of ice, and you instantly feel the cold of the ice cube. This is so counter intuitive and so cool both ways. In less than a minute, you can use the warmth from your fingers to slice through solid ice. How does the warmth of your fingers reach the ice (and vice versa) you ask? The answer:

Pure Graphene (aka "Pyrolytic Graphite").  This piece is the perfect size and shape to be used as an Ice "Knife".  We think this product is amazing.  Touch it to a piece of ice, and you instantly feel the cold of the ice cube. This is so counter-intuitive and so cool - both ways. In less than a minute, you can use the warmth from your fingers to slice through solid ice.  How does the warmth of your fingers reach the ice (and vice versa) you ask?  The answer:  Pyrolytic Graphite (Graphene).

Pyrolytic graphite (Graphene) is an atomic-scale hexagonal lattice made of carbon atoms.  It is about 200 times stronger than the strongest steel. It conducts heat and electricity very efficiently and is (nearly) transparent (though it appears black to the eye).

We can supply you with your own piece of Pyrolytic graphite that has been manufactured into excellent dimensions to try cutting ice for yourself: our 'Ice Knife' product measures 100 mm x 25 mm x 1.2 mm.

For an excellent overview of pyrolytic graphite, check out the video below.

The 'Ice Knife' comes in a presentation box.

Plus, what other knife do you know that will levitate above N52 magnets indefinitely, without any form of outside assistance?

Recommended for Age 12 & Up (with adult supervision)

Doesn’t last long
Flavor Name: Peanut Butter, Size: 4 Ounce (Pack of 1)
Both my dogs chewed these up way too fast. Disappointing because I was hoping it would last longer. No odor. Size as expected. They seem to like the taste and had no issues in digesting it
