Is the Penari Saber part of the Star Wars Universe, or is it just a random piece of Fan Fiction not recognized by George Lucas?

For those unfamilar with the Penari Saber, it was suppose to have been invented 2000 years before Phantom Menace. Built by Jedi scientist Crutus Penari. This yellow bladed saber was said to be able to cut through other lightsabers, and was ultamtely ordered to be dismantled because the Jedi Council of that time found it to be too much of a threat.

Dose anyone know of what story, novel, or comic book the Penari Saber origionated from, or is it just some piece of fan-fiction that is by no means cannon in the Star Wars Universe.

The concept of a lightsaber cutting through another saber fasinates me. How would it function? Dose it disrupt the energy flow of a normal lightsber, causing the Penari to slip through a normal energy blade? Thus would it be useless to block with because as the Penari passes through the other blade, that other blade would be left unaffected and intact as it continues it's arc towards you. Try to do an over head block as the Penari slips through the other blade. ouch

Or.... dose the Penari so Severly disrupt a normal blade that it causes the other blade to shut down, thus damaging the lightsaber by causing some kind of energy feedback frying the electronic innards of the saber.

Any ideas? Dose anyone know anything about it?
