I switched from regular pencils to a mechanical one over the summer and I love it! Although I still start my drawings with a sketch using a 3H pencil, which allows me to fully erase my mistakes. My favorite eraser for this stage is my 'Generals tri-tip' eraser. It is soft and gentle on your paper but erases almost anything! Once I'm happy with my sketch I switch to a 0.5 mechanical pencil with 2b lead for the remainder of the drawing. At this stage I start using a blending stump and my Faber-Castell detail pencil eraser. I love that I can sharpen this eraser which helps keep my detail work clean.
