Testing a new ball point pen. I like to have one on me as it is quite practical for unpredicted sketching in public places. No need to mess with pencils, erasers or knives to sharpen the pencils. Another reason why I like to draw with either pen and ink or just ball point pen is the fact that I cannot erase anything. So, the line has to go where it needs to go for the image to make sense. Not much second guessing which means I really have to pay attention. Good exercise.
