Our common pencils have a writing core of a mixture of graphite and clay, enclosed in a (generally) wooden body. This body is made in two parts intended to be joined together. The outer shape may be round, hexagon, triangle etc, as wished. In the middle of each half is a groove to hold the lead snugly. Glue is used to hold the two halves together, and also the writing graphite core.
Only very seldom, and with rough treatment will the two halves of the body separate.
