Hey guys,
This is this biggest collection of geek knowledge I have currently. Well I need to ask if anyone knows of the name of this device I saw on Cool Tools (DIY Network w/Chris Grundy). Its a propane torch used for cutting design into stone. Uses propane as a fuel + air to superheat rock so that it will chip off in a uniform and predictable manner. Used for carving hard stones and rock that doesnt contain excess H2O.

I've tried googling and I havent come up with anything. *duhhhhrrrrrr*

Any help or leads to episode or device name are superbly appreciated!

Cheers,
The dr.
