Lead is a metal but pencils do not contain lead. The gray material in pencils is graphite which is a form of carbon. In most pencils a metal ring binds the eraser to the wooden shaft. That could be detected but the graphite would not. A mechanical pencil made of metal or having some metal parts could be detected but not because of the graphite contained therein.
