The latest skis from the small Swiss ski maker Zai are the Spada skis which are named after the Romansh word for Sword. The skis are hand made and feature a core made of specially treated granite from the Grisons canton as opposed to the normal wooden or titanium cores of skis. The granite is treated with a process called Technocarbon which allows it to be bendable and retain the same strength which results in incomparable agility, grip and smoothness.
