A friend skated one during highschool, man that was probably 14 years ago now. It was the first and only one I have ever seen. The deck was metal but the nose and tail had replaceable wooden ends you could plug into the metal deck.
It didn't snap or chip but it did bend and dent really badly right from the start. The wooden ends were also prone to falling out. Every time he tried a trick the board made a loud sharp clang, it way louder than a normal board. It was a piece of shit.
