Sharp by name…
“In 1822 two Britons (Sampson Mordan and John Hawkins) developed and patented the first mechanical pencil mechanism to propel a writing core thru a shaft allowing people to write with it. We call this device a mechanical pencil. Growing in popularity across the globe, Tokuji Hayakawa, a metal worker in Japan refined the casing using metal and sold his version as ‚ÄúEver-Sharp Pencil‚Äù. It sold in such great numbers that he founded a company based on the name of the pencil… Sharp.”

I suppose mechanical pencils had to be invented by _someone_. I used to like using a ‘clutch pencil’ with the chunky lead when I was at school. The diyplanner site has a range of calendar and diary designs that can be downloaded as PDF files. The “A4 set”:http://www.diyplanner.com/files/diyplanner_cal_a4.pdf might be useful for _logging_ activity as it happens as well as planning.
