I am debating with myself whether I should buy one of these pencils as aChristmas present for myself. My scruples have more to do with the notion of "buying a present for yourself" than with the pencil per se.
It is a reproduction of one of the first pencils ever. The original dates from 1526 and mentioned by Gessner in a book about fossils. It takes 5.6 mm lead refills, weighs 0.5 oz, is 6 inches long, and an award winning pencil from Cleo Skribent of Germany. It is made in Germany.
The led is a lot better than that of the original was. Technology has advanced. So, it is usable.
