A writing instrument is ergonomically adjusted to the position of a user's hands. The writing device has a substantially tubular shaft along a main axis, a terminal part at the rear end of the shaft and a substantially conical tip at the front end of the shaft. Using the terminal part, the tip can be pivoted (inclined) in a controlled manner in relation to the shaft in a plane containing the main axis. Alternatively, an angle of inclination of a cone axis of the tip can be adjusted in relation to the main axis.
