This is what gives you smooth consistent lines when you hold a pencil and drag it across paper. Because graphite is soft and brittle, a casing is required to hold the material. Artists use graphite, not just in pencil form, but in powder form too. In powder form, graphite can be applied to paper using a brush, sponge or tortillion.

Good question. Graphite powder is a good lubricant especially in cold weather as it works well to prevent a lock from freezing. However, in the UK it is very humid even when cold. This freeze / thaw combination caused the graphite to congeal and get sticky. On top of that, graphite powder is really messy when trying to apply to a padlock mechanism.
