Oldschool

Until the beginning of the 90s many proskaters skated their own promodel deck. These decks are also referred to as shaped decks. Some had for example a narrow nose and a wide tail. Other decks had a distinctive shape like the Christian Hosoi promodel reminiscent of the shape of a hammerhead.
Even with these decks you can do almost every trick. This is however much more difficult than with the modern forms of the nineties.
