Graphite Block Sawn from Solid Natural Graphite

Solid natural graphite, like the Borrowdale graphite once sawn into pencil sticks, is soft enough to saw and file to shape. Saw a squared block from a sound lump and file its faces flat. The picture: our diagram, a lump with saw lines and the block cut from it.
