SK1 (which stands for Skencil or Sketch) is a vector format associated with the SK1 drawing program, which was designed for Linux platforms and had its last release in 2009. As opposed to other competing programs, such as Corel Draw or Adobe Illustrator, SK1 is open source, so it can be downloaded and used for free while offering similar features.
