What material is capable of holding a knife edge but isnt conductive?

[mwmorph]

I'm creating a project that requires a non conductive or capacitive material that will hold a knife edge, any hints?

TIA

Chest cavity?

Non conductive - ceramic knives?

Non capacitive...uhh

ice

Plastic? Alluminum?

 

[BigJ]

Fiberglass Knife will do it.

Sorry, the laptop keyboard is a little odd.

I did not know they made ceramic knives but now I do, zirconium dioxide. Wonder what the cost of that material is.

ceramic knives are quite expensive.

Nah, just college, ME Major. I have to design a nonconductive cutting type tool.

If I was in prison, I'd be asking how to make that infamous paper prison shank.

ceramic

Bone or flint, if you want a more traditional feel. Flint will give a better edge. Obsidian is another option...razor sharp, and much more robust than flint.

 

[tailes151]

Obsidian holds its edge better than steel.

 

[ItTheCow]

Diamond? Although, what exactly are you cutting?

 

[tasmanian]

If you do obsidian you can collect it from places around you. Well depending on where you live.

rubber. /thread.

and they're more brittle, too.

but they are much stiffer. generally speaking, anyway.

if you give us some parameters (ie, why you need a non conducting knife), that would help.


as people have previously mentioned, plastics and ceramics are the way to go for non conducting materials. stone will certainly do (it is a ceramic, technically).

Ceramic, volcanic stone.

At what voltages? Everything starts to conduct at high enough voltage.

If you're just worried about shorting out a few nine volts in your pocket or getting through airport security with a knife, this is your ticket!
