All through my years in school, I hated using those old yellow pencils that needed to be sharpened all the time. It seemed like the tip of my pencil would always be too dull for my liking, or would always break off whenever I needed it the most. When I discovered the joy of using a mechanical pencil, though, those problems became a thing of my past.
By far, the mechanical pencil of my choice these days is the "M-402" model from Zebra. This pencil uses 0.5mm lead, which is always sharp, and is the perfect size for any writing or drawing that I might want to do.
It's stainless steel barrel and rubber finger grip fit well in my hand, and its sturdy clip helps to ensure that my pencil won't be lost when I'm carrying it in my pocket.
Underneath the cap of the pencil you'll find a handy eraser, and beneath that eraser is a tube where you can store several extra pieces of lead.
I'm not one to leave well enough alone, though. I've found that I can improve upon these pencils, and make them even more comfortable for me to use by the addition of an extra foam, or rubber finger grip. With one of those in place, I could write comfortably for hours if needed.
If you hate dull pencil points as much as I do, do yourself a favor an check out the Zebra M-402 mechanical pencil at your local office supply store. For right round $5, it's hard to beat.
