Would highly recommend this KuruToga mechanical pencil: https://www.amazon.com/Uni-Ball-KuruToga-Mechanical-Pencil-Starter/dp/B0026ICM1E The lead automatically rotates as you write, so you are always writing with a sharp edge. I'm usually the kind of guy to lose writing utensils left and right, but I have held on to this one for over a year now. It writes like a dream.
