I spend a lot of time working with spreadsheets and other electronic documents. So you would not guess that pencils were important to me. But the work I do is creative and requires carefully considered stages in its creation. That is done with a pencil and plain white ruled paper. The eraser is important too. I have high quality bulk erasers but I am impatient and usually just use the one on my Pentel. I am not young, in my mid-eighties, and am impatient and forgetful. Sometimes I become angry when I have misplaced all my Pentels and have no way to proceed with my work. Well, since it is important, I ordered another dozen pencils. And now, if none are at hand, I just open the box and take another.
