Abstract: A writing instrument has a nib that can retract automatically upon release of a grip on the writing instrument. The writing instrument has one or more leaves that can be flexed to push the cartridge towards the front end of the writing instrument to expose the nib. A spring applies a force on the cartridge to automatically retract the nib when a grip on the writing instrument is released.
