a brush made for sketching using half tones, relies on dual brush feature to work properly
i'm too tired to give this a good description, but it uses the dual brush feature to let you have 2 half tones in one brush depending on your pen pressure!
in my experience it's a fairly finnicky brush, always make back ups incase you forget how to go back. or dont :3
examples of it :)
