The nib of the pen is bipart. Varying the pressure creates a variable splay. On a multitouch surface, both contact points are sensed. The upshot is a tablet can be used to create fine calligraphy involving realtime variable linewidth. The nib can also be manually set to a fixed width, for that type of artistic penmanship.

If you want to do serious art on your tablet, you need one like this... [neutrinos_shadow, Oct 26 2016]

But the tip of the stylus is already pressure sensitive, so there is no need to make a physically "spreading" tip, when it can be done with software.

^ perhaps, but that wouldn't do anything for angle-of-nib stuff.

//assert greater pressure// Actually, I'm trying to define a new style of writing - increase nib/brush width with greater pressure, giving integral variable bold.

Wacom digitisers have 5 degrees of data as standard (x-position, y-position, tip pressure, x-tilt, y-tilt) and stylus rotation as well if you spring for the fancy "art pen". As I said, this can easily be done with software. I suspect you just need to buy a better tablet...
