Like GHW Dukandar, GHW Adhiapak is a real-life, hand-written font from a real, human being - my Punjabi teacher, hence the name GHW (Gurmukhi Hand-Written) Adhiapak (teacher).
Above, you can see it in Article One of the Universal Declaration of Human Rights.
The top line is broken in a number of places but is sufficiently constant to show the level of after-writing line drawing that goes on. Also note that the ਲ is that of an experienced writer in this style (I write my ਲs like that as well).
Below, you can see some of the variants of GHW Adhiapak.
There are nine weights of the regular font, from Thin, through Book and Medium to Bold, Heavy and Black.
There is also a 'Chisel variant, mimicking a flat-tipped marker, such as you might use for small-sign writing.
Finally, there are the Marker variants - a more rectangular tip, still at an angle - along with their corresponding 'tip' fonts.
