Nice set of advices, save for a disturbing novelty sharpener. In some old school design bureau I once noticed a curious style of sharpening, where the shaved wood would be tapered at unusually extended length (over one inch) instead of just one cm. This style would be hand cut. I guess, the utility is probably two fold - this makes the bottom part of the pencil skinier so it's easier to handle it with those bulky drafter's rulers, also it saves time to keep the tip resharpened, as less wood needs to be shaved off during the work. Additionaly, with longer slope it's probably easier to keep the tip pointy by rolling it on the side. The ugliest sharpening job comes with those stubby Teconderoga school pencils, little core to use and steep tip.
